+Change Log:
+===========
+
+
+---------------------------------------------------------------------------
+
+Version: 3.21 Fri 30-Jul-93 Jonathan Roach
+
+Turned into module for first time.
+
+---------------------------------------------------------------------------
+
+Version: 3.22 Thu 26-Aug-93 Owen Love
+
+* Improvement in the wording of the error messages stored in the message
+file as part of the Libra project.
+
+---------------------------------------------------------------------------
+
+Version: 3.23 Wed 22-Sep-93 AGodwin
+
+Checked in TestSrc directory. POST currently disabled for normal startup
+and should be available only when POSTbox display is attached.
+
+---------------------------------------------------------------------------
+
+Version: 3.24 Thu 30-Sep-93 AGodwin
+
+Checked in updates to POST : should be fully working version.
+
+---------------------------------------------------------------------------
+
+Version: 3.25 Mon 18-Oct-93 Owen Love
+
+Changed 'Bad parameters for *Save' error message that was incorrect
+
+---------------------------------------------------------------------------
+
+Version: 3.26 Thu 21-Oct-93 Jonathan Roach
+
+
+ (19-Oct-93) TDobson
+ Fix MED-00523: Remove pointer if would be completely off LHS of
+ screen, otherwise can upset display if it straddles hsync pulse.
+ Fix MED-00637: Creating dynamic area of zero maximum size now
+ works. Screen mode 32 changed to NColour=63 and ModeFlags=0,
+ like all other numbered 256 colour modes.
+
+---------------------------------------------------------------------------
+
+ * Changed startup code to give memory size in megabytes rather than
+ kilobytes. Change made (conditionally) in NewReset by Bruce Cockburn
+ on 04-Nov-93.
+
+
+---------------------------------------------------------------------------
+
+Version: 3.27 Mon 15-Nov-93 Jonathan Roach
+
+ (21-Oct-93) SCormie
+ *Configure MouseType should have called OS_Pointer.
+ (25-Oct-93) SCormie
+ NewReset now waits up to 1 sec for keyboard present.
+ (25-Oct-93) TDobson
+ Fix bug MED-00811 - initialise SpriteSize to zero on reset.
+ (25-Oct-93) JRoach
+ Fix bug MED-00680 - *Save syntax message not tokenised properly.
+ (26-Oct-93) JRoach
+ Fix bug MED-00570 - delete-power-on gives 1997. Problem was
+ delete-power-on set base to 1994 and so when the modulo of '3' came
+ out of the clock the kernel thought it had to be 1997.
+ (26-Oct-93) TDobson
+ Fix bug MED-00301 - mode selector block now alternates between two
+ overlapping ones, so that returned mode number changes each mode
+ change (although if someone goes eg M%=MODE:MODE 12:...:MODE M% it
+ will use the block specified by M%).
+ (28-Oct-93) AGlover : vduswis, vdudriver, vdugrafj, vdugrafk
+ Bugfixing session on sprites. Major points:-
+ Screensave works, and gives old format sprites where possible.
+ Screenload works, and no longer believes the mode number in the
+ sprite - it will always build a mode selector to suit the sprite.
+ EIG 0 and EIG 3 sprites supported - fixes DragASprite leaving
+ trails on-screen in these modes.
+ Mode 32 is now the monitor type 4 256 colour substitute mode.
+ GetSprite(User) ensures no LH wastage on new format sprites.
+ Screensave now copes with saving a full entry 256 colour palette.
+ Whenever possible GetSprite will make an old format sprite - if
+ you must have a new format sprite make it first with CreateSprite.
+
+ While there are four of us intermittently touching bits of the kernel
+ please say which files you've actually altered. Thanks. amg
+
+ (03-Nov-93) AGlover : vdugrafj
+ Change substitute mode numbers used for 90 x 90 dpi sprites to 25-28
+ instead of 18-21.
+
+ (04-Nov-93) JRoach : GetAll, Kernel
+ Enable IncludeTestSrc and make Reset vector for resetting work in
+ conjunction with the test source.
+
+ (08-Nov-93) TDobson : vdudecl, vdudriver
+ Complete kernel support for DPMS.
+
+ (10-Nov-93) TDobson : source.pmf.osbyte
+ Fix bug MED-00963: INKEY(-256) now returns &A5.
+
+ (11-Nov-93) TDobson : source.vdumodes
+ Fix bug MED-?????: mode 32 now same timings as modes 29-31.
+
+ (12-Nov-93) AGlover : source.vdugrafg
+ Fix bug MED-01112 : 32K/16M sprites not working with SpriteOp ReadPixelColour (41)
+ Fix bug MED-????? : Correct the routine which bounces palettes on new format sprites
+
+ (13-Dec-93) BCockburn : Middle, Source.PMF.OsInit, Hdr:VickySpace
+ Inmplemented ReadSysInfo 4 to do the Ethernet address. This meant changing
+ the reading of the 64 bit thing (in osinit) to store all of it rather than the
+ 48 bit version. Moved the 48bit trimming code the the implementation of
+ ReadSysInfo 2.
+
+---------------------------------------------------------------------------
+
+Version: 3.28 Fri 17-Dec-93 Jonathan Roach
+
+
+ (18-Nov-93) AGlover : source.vdugrafh, source.vduswis, source.vdudriver, source.vdugrafj
+ Fix bug MED-01130 : GetMaskSpWidth was going wrong when mask exactly fitten in a word
+ Change handling of sprite type so that unknown types are handled as 32bpp - will make
+ life easier for people adding new types that the OS doesn't handle.
+
+ (23-Nov-93) AGlover : source.vdugrafg, source.vdugrafh, source.vdugrafi
+ Fix bug MED-01281 : return an error when I should for spriteops given new format
+ masks.
+
+ (24-Nov-93) AGlover: source.vdugrafg
+ Fix bug MED-????? : sprite name matching code was being broken by changed
+ lowercase macro. Code now uses uk_lowercase which retains the original
+ behaviour of the macro keeping the sprite stuff compatible with 3.10
+
+ (25-Nov-93) TDobson: source.vdumodes
+ Fix mode definition for mode 47 (PCEm mode 360 x 480) to have sync polarity 3,
+ so it gives correct height on VGA-only monitors.
+
+ (26-Nov-93) SCormie: Source.PMF.key, Source.PMF.osinit
+ Keyboard driver and key handler now trigger each other correctly during reset.
+ Change default serial threshold from 9 to 17.
+
+ (30-Nov-93) AGlover: source.vdu23, source.vduwrch
+ Fix bug MED-01141: Split CompileTextFgBg into two separate routines and only call
+ the one actually relevant. This prevents spurious colour changes when a text colour
+ set by OS_SetColour is changed using VDU 17 or VDU 23,17 (what used to happen is
+ that because the Fore/Back Col and Tint words didn't produce the colour in use (which
+ had been modified directly by OS_SetColour) it was replacing it with whatever the
+ ForeCol and Tint produced. Note: Doing a VDU 23,17 before the first VDU 17 will still
+ go wrong - but I don't think it's worth fixing.
+
+ (30-Nov-93) TDobson: source.vdumodes
+ Change XEigFactor for games modes 48,49 to 2 (from 1) at the request of Ran Mokady.
+
+ (01-Dec-93) TDobson: source.pmf.osword
+ Fix bug MED-00355: OS_Word(&0F) no longer requires a terminating
+ character after string (it now pushes the string on the stack and
+ terminates it, before calling the TerritoryManager).
+
+ (01-Dec-93) TDobson: NewReset
+ Fix bug MED-01513: now prints eg "RISC OS 10MB" on startup.
+
+ (02-Dec-93) TDobson: ModHand
+ Fix bug MED-01229: now uses 8 bytes of unplug CMOS for podules, + 1 for network card
+
+ (06-Dec-93) JRoach: NewReset
+ Correct mouse step default to 2 for faster mice we'll be using.
+
+ (07-Dec-93) AGlover: source.vdugrafj, source.vdugrafk
+ Fix bug MED-?????: make sure screensave and getsprite(user) don't permit palettes
+ on sprites which it can't force back to an old screen mode
+
+ (09-Dec-93) TDobson: source.vdudriver, source.vduswis
+ Use Roger's algorithm for default XEigFactor, YEigFactor for mode selectors.
+
+ (13-Dec-93) TDobson: GetAll
+ Set AddTubeBashers flag to FALSE.
+
+ (15-Dec-93) TDobson: GetAll, NewReset
+ Set DebugROMInit and DebugROMErrors flags to FALSE.
+ Fix bug MED-01774: Change default FontSize to 64K.
+
+---------------------------------------------------------------------------
+
+Version: 3.29 Tue 21-Dec-93 Owen Love
+
+Changed 'Memory cannot be moved' error message.
+
+---------------------------------------------------------------------------
+
+Version: 3.30 Thu 27-Jan-94 Jonathan Roach
+
+
+ (21-Dec-93) AGlover: arthur3
+ Fix bug MED-01583 - *eval 9999999999999 was calling msgtrans twice to return error
+
+ (06-Jan-94) TDobson: Kernel, Source.PMF.Key, SWINaming
+ Added SWI OS_Reset - part of fix for MED-01397.
+
+ (10-Jan-94) BCockburn: Middle
+ Fixed Ethernet address generation to use the correct base
+ (&0000A4100000) value rather than the value &0000A4000000 as found
+ in the Dallas chip itself.
+
+ (10-Jan-94) TDobson: source.vdudriver, source.vduswis
+ Fixed bug MED-00563: invalid mode selector should return error from
+ mode change, not select mode 0.
+ If current monitor type is a file, now uses VGA substitute table for
+ unavailable mode numbers - eg if you select mode 16, you now get
+ mode 27, rather than mode 0.
+
+ (10-Jan-94) TDobson: source.vdudriver
+ Fixed bug MED-00483: "mode selector" not on a word boundary (eg
+ sprite mode word) is now not offered round to Service_ModeExtension,
+ so should now give error, rather than data aborts.
+
+ (12-Jan-94) JRoach: GetAll
+ Fixed bug MED-00585: configured language wasn't 10, and now is.
+
+ (13-Jan-94) TDobson: GetAll, ModHand
+ Introduced conditional flag RMTidyDoesNowt - if true (which it is on Medusa),
+ then RMTidy returns having done nothing. This is because it would always
+ fail anyway, because FSLock always refuses to die. Fixes MED-02125.
+
+ (14-Jan-94) SCormie: source.PMF.osinit
+ Changed combo chip configure sequence so that 710 configuration doesn't put
+ 665 into a strange state if receiving at the same time (caused chip to generate
+ an interrupt which could not be cleared.
+
+ (14-Jan-94) JRoach: Arthur2
+ Changed GSInit/GSRead to use its stack memory as a wrapping buffer.
+ This means GSInit doesn't need to flatten it before starting which
+ means recursive calls the GSTrans work.
+
+ (17-Jan-94) TDobson: ARM600, ChangeDyn
+ Put in semaphore, so that OS_ChangeDynamicArea will fail if it is already threaded.
+ (Data abort handler clears it, in case area handler goes bang!)
+
+ (17-Jan-94) TDobson, AGlover: source.vdugrafj
+ Fixed the 21-Dec-93 fix so it assembles and hopefully works!
+
+ (18-Jan-94) TDobson: ARM600, Kernel, SWINaming
+ Added soft copy for MMU control register, and SWI OS_MMUControl to update it.
+
+ (19-Jan-94) AGlover: source.vdugrafg
+ Fix bug MED-02210 - plot mask for 1bpp masks was going wrong when plotting clipped.
+
+ (19-Jan-94) JRoach: NewReset
+ Correct CMOS default for textured window background to match the CMOS spec.
+ (The spec says set bit 7 of &8c to 0 to turn on textured window backgrounds).
+
+ (19-Jan-94) JRoach: NewReset
+ Correct CMOS default for desktop font to '8' which is still Homerton.Medium.
+ Changed needed as Darwin has been removed and so the numbers change.
+
+ (19-Jan-94) TDobson: ARM600
+ Fixed bug MED-02452: make BangCamUpdate check if oldaddr=newaddr,
+ and don't remove page from old address if so.
+
+ (19-Jan-94) TDobson: source.vdudriver
+ Changed notional operational range for VCO to 55-110MHz (from 40-80MHz).
+
+ (21-Jan-94) TDobson: ARM600
+ Changed ROM access speed to 156.25ns (from 187.5ns)
+
+ (21-Jan-94) TDobson: source.vdudriver
+ Changed ComputeModuli to only use R-values up to 16 (not 64), to
+ improve minimum comparison frequency.
+ Change FIFO load position algorithm to use table produced by Peter
+ Watkinson.
+
+ (24-Jan-94) TDobson: GetAll, source.vdudriver, source.vduswis
+ Conditionally reversed change to XEig/YEig algorithm back to what it was
+ in 3.27.
+
+ (25-Jan-94) TDobson: source.vdudriver
+ Fixed FIFO load position table to use correct units.
+
+---------------------------------------------------------------------------
+
+Version: 3.31 Tue 08-Feb-94 Tim Dobson
+
+ (28-Jan-94) AGlover: syscomms, source.vdugrafj
+ Fix bug MED-01570 (syscomms), and various bugs reports involving
+ 1bpp 2 x 2 eig modes (vdugrafj: sanitizesgetmode was mishandling
+ double pixel modes)
+
+ (28-Jan-94) TDobson: source.vdumodes
+ Update kernel's hard-wired mode tables to use new VCO range.
+
+ (28-Jan-94) TDobson: TickEvents
+ Fixed bug MED-02498: OS_CallAfter/Every and OS_RemoveTickerEvent problems.
+
+ (31-Jan-94) TDobson: TickEvents
+ Fixed register corruption in above fix.
+
+ (01-Feb-94) AGlover: hdr:sprite, vdugrafdec, vdugrafj, vdugrafk, vdugrafl
+ Fix bug MED-02160. Make switching output to, and screenloading of, a
+ 256 colour 8bpp sprite work. The hdr change is because the value of
+ MaxSpritePaletteSize has been updated.
+
+ (03-Feb-94) TDobson: ARM600, ChangeDyn, GetAll
+ Fix bugs MED-00793, MED-01846. Dynamic areas which may require
+ specific physical pages must now have a new bit set in the dynamic
+ area flags. As a result, other areas can perform large grows in one
+ chunk, rather than being split up, because it is not necessary to
+ set up the page blocks etc. Therefore a) dragging RAMFS bar is much
+ faster and b) there's no chance that intermediate reinits of RAMFS
+ can steal pages that were to be used for subsequent chunks.
+
+---------------------------------------------------------------------------
+
+Version: 3.32 Mon 14-Feb-94 Tim Dobson
+
+ (08-Feb-94) AGlover: source.vdugrafh
+ Fix bug MED-01885. WritePixelColour wasn't working correctly for
+ 8bpp full palette sprites.
+
+ (09-Feb-94) TDobson: Messages
+ Fix part of bug MED-02389 by changing system heap full message.
+
+ (10-Feb-94) AGlover: source.vdugrafh
+ More on MED-01885. AddTintToColour decides what to do by NColour, rather
+ that SprRdNColour which is correct for Write/ReadPixel in sprite.
+ Set NColour to SprRdNColour for the call and then restore it afterwards.
+ The scope of the bug was more than first thought - it affected writing to
+ any 8bpp sprite in anything other than an 8bpp screen mode.
+
+ (11-Feb-94) TDobson: NewReset
+ Limit maximum size of RAM disc to 16MB, because FileCore can't cope
+ with some larger sizes.
+
+---------------------------------------------------------------------------
+
+Version: 3.33 Tue 15-Feb-94 Tim Dobson
+
+ (14-Feb-94) TDobson: NewIRQs
+ Fix bug MED-02859 - Unknown IRQ code now copes with DMA IRQs.

+
+* s.ARM600 - Fixed MED-03854, enable MMUC_F bit in MMU control register by
+ default (actually ARM700 specific so that coprocessors run at FCLK speed,

+
+---------------------------------------------------------------------------
+
+Version: 3.89 Tue 06-Dec-94 Steve Cormie

+ length of all commands exceeded the buffer size (512 bytes claimed from
+ stack) then the stack was corrupted.
+* s.Arthur3 - Fixed MED-04034: New lines required after *Status and *Configure

+
+---------------------------------------------------------------------------
+
+Version: 3.92 Thu 15-Dec-94 Alan Glover
+
+* s.vdu.vdugrafh - this oops lark is contagious. Really do the changes I

+ sources together.
+
+---------------------------------------------------------------------------
+
+Version: 3.93 Mon 19-Dec-94 Richard Manby
+

+
+---------------------------------------------------------------------------
+
+Version: 3.98 Thu 19-Jan-95 Steve Cormie
+
+* s.Kernel - Fixed MED-04367: R9 was being corrupted by ExtensionSWI handler
+ before calling the module SWI handler (PRM says that R0-R9 are passed from
+ the SWI caller). This has been broken for a long time (it is also present
+ in RISC OS 3.11 and possibly earlier).
+
+---------------------------------------------------------------------------
+
+Version: 3.99 Fri 20-Jan-95 Alan Glover
+
+* s.vdu.vdugrafe, s.vdu.vdugrafdec, s.getall, hdr.kernelws - Fix MED-00001:
+ Flood fill now attempts to use rma, and use two-word entries in the queue
+ allowing it to overcome the old 1024 line limit.
+* s.getall, s.morris - add warning messages when switch settings indicate
+ a version is being built that can't be tested by soft-loading on a RiscPC
+ (guess who fell for it!).
+* s.getall, hdr.kernelws - Add Audit trial debugging for MED-00001: this should
+ be turned off (med_00001_debug) in s.getall once the fix has been tested
+* hdr.riscos - change a character in a comment which objasm was sulking about
+
+---------------------------------------------------------------------------
+

+ MED-04451
+
+---------------------------------------------------------------------------
+
+Version: 4.01 Wed 01-Feb-95 Richard Manby

+ active before killing it.
+
+---------------------------------------------------------------------------
+
+Version: 4.05 Tue 07-Feb-95 Steve Cormie
+
+* hdr.KernelWS, hdr.PublicWS - Removed the change made in version 4.03.
+ SVC stack size moved back to 8K as changing it makes other modules
+ eg. FileSwitch, no longer work on older operating systems.
+
+---------------------------------------------------------------------------
+
+Version: 4.06 Tue 07-Feb-95 Richard Manby
+
+* s.PMF.osinit
+
+Optimisation: New routine Configure37C665 used instead of Configure82C710.
+Since all the machines that Black is targetted for use the SMC 665, there is
+no point assembling code that can cope the 82C710/82C711 as well.
+
+For Stork: Added code to initialise various PowerControl latches so that
+the machine powers up to a sensible state and will function (sort of) if
+the portable module is unplugged.
+
+---------------------------------------------------------------------------
+
+Version: 4.07 Wed 08-Feb-95 Steve Cormie
+
+* s.Arthur2 - Fixed MED-04528: OS_SetVarVal code was looking up the error

+Version: 4.09 Wed 15-Feb-95 Steve Cormie
+
+* hdr.KernelWS - Part of fix for MED-04611: Added CLibCounter for use by
+ Shared C Library tmpnam function.
+
+---------------------------------------------------------------------------
+
+Version: 4.10 Wed 15-Feb-95 Richard Manby
+
+* s.GetAll } Conditionally changed the RISC PC ROM speed setting code
+* s.ARM600 } to set burst mode ROM access. See flag RISCPCBurstMode.
+ If false, this will generate non-burst mode code as used
+ by all earlier versions.
+
+---------------------------------------------------------------------------
+
+Version: 4.11 Thu 16-Feb-95 Richard Manby
+
+* s.Kernel Fixed stack inbalance in SWI despatch code - Pull "R9"
+executed prior to entering modules made conditional on actually calling
+the code, as if code is not called, we drop into VectorUserSWI code
+which also pulls R9. Fixes MED-04655.
+
+---------------------------------------------------------------------------
+
+Version: 4.12 Tue 28-Feb-95 Richard Manby
+
+* s.ARM600 Amount of space allowed for screen limited to 16MByte (as
+requested by Tim Dobson).
+
+---------------------------------------------------------------------------
+
+Version: 4.13 Wed 01-Mar-95 Richard Manby
+
+* s.ARM600 Code added to check processor type before setting burst mode on
+a RISC PC. If processor type is ARM710, burst mode cannot be used.
+Any other processor, ie ARM610, ARM710A etc uses burst mode.
+NB This has no effect on Morris which uses seperate code.
+
+* s.Morris - altered conditional to switch proper Morris start code in as the
+default, rather than the code for early damaged Morris'.
+
+---------------------------------------------------------------------------
+
+Version: 4.14 Wed 01-Mar-95 Richard Manby
+
+* s.GetAll Flag RISCPCBurstMode set true.
+

+
+---------------------------------------------------------------------------
+
+Version: 4.16 Mon 06-Mar-95 Richard Manby
+
+* s.ARM600 zeroed VRAMSize for Morris based machines - fixes DForths bug MED-?????
+ also, after inspection of RPC code, initialised IOMD_VIDEND.
+
+---------------------------------------------------------------------------
+
+Version: 4.17 Tue 07-Mar-95 Alan Glover
+
+* s.GetAll: Turn off the MED-00001 audit trail flag.
+
+---------------------------------------------------------------------------
+
+Version: 4.18 Wed 08-Mar-95 Richard Manby
+
+* s.ARM600 In Morris specific IOMD register initialisation code - VIDMUX
+ register set for 'Japanese' format sound DAC's, cos Kryten and Stork
+ both now have 16 sound.
+
+* s.NewReset CMOS RAM reset code now sets 16bit sound for all Morris based
+ machines and RISC PC's that look like Sugar/Rimmer. Normal RISC PCs set
+ for 8bit sound.
+
+ Above two changes fix MED-04831 and MED-04646.
+
+* s.os.osinit Fixed Stork detection code.
+
+
+---------------------------------------------------------------------------
+
+Version: 4.19 Wed 08-Mar-95 Richard Manby

+
+---------------------------------------------------------------------------
+
+Version: 4.20 Fri 10-Mar-95 Steve Cormie
+
+* s.Kernel, s.GetAll: Conditioned out fix for R9 corruption in ExtensionSWI
+ handler (conditional on FixR9CorruptionInExtensionSWI) because CC's
+ !SpellMod and possibly others rely on broken behaviour.
+* s.NewReset: Added default CMOS configuration for CDROMFSCMOS.
