  RPCEm update.
* Register allocation in default ErrorV handler fixed - problems occured when
  callbacks were triggered on way out.
* OS_Byte 19 didn't manipulate interrupt disable flag correctly in 26-bit
  builds.
* Stray bit of debugging left in sprite code many years ago removed.

Version 5.23. Not tagged

Details:
  The Kernel will now compile to produce a pure 32-bit system if No26bitCode is
  set to TRUE.
  If No26bitCode is FALSE, then the Kernel will be a standard 26-bit Kernel,
  although some internal changes have taken place to minimise compile
  switches between the two cases. See Docs.32bit for more technical info.

  The hardest part was the flood-fill...

Other changes:
  Pointer shape changes now take place on the next VSync, rather than actually
  WAITING for the VSync. Turning the Hourglass on shouldn't slow your machine
  down by 5% now :)

  Lots of really crusty pre-IOMD code removed.

Admin:
  Tested in 32 and 26-bit forms in a limited desktop build. Basically, this
  will need to see a lot of use to iron out difficulties. I'd like anyone who
  has a non-frozen project to at least attempt using this Kernel.

Version 5.23. Tagged as 'Kernel-5_23'

Right arrow on a remote also acts as Delete.

Version 4.98. Tagged as 'Kernel-4_98'

Kernel now uses PortManager to set TV_Mode GPIO line, and updates it on every mode change, rather than doing it once based on the monitor lead ID.

Requires PortManager, and required if PortManager is present.

Version 4.92. Tagged as 'Kernel-4_92'

Doesn't force CMOS setting of sync and monitortype on NCs/STBs.
Accepts HClockSelect parameter (number 9) in VIDC lists. Uses this to
determine whether to use HCLK or not, rather than abusing
Service_MonitorLeadTranslation.
If DontUseVCO flag is set, then VCLK will not be used - only RCLK (or HCLK if
requested).

Version 4.86. Tagged as 'Kernel-4_86'

Version 4.84. Tagged as 'Kernel-4_84'

Version 4.83. Tagged as 'Kernel-4_83'

* Integrated Ursula fast service call dispatch code.
* Added Interruptible32bitModes from Ursula.
* Stopped allowing ROM modules (other than the Kernel/UtilityModule) to write
  to the hardware vectors in 26-bit mode.

Version 4.81. Tagged as 'Kernel-4_81'

Version 4.72. Tagged as 'Kernel-4_72'

ROM speed not taken from the Machine header file.  POST can now exist in a softloaded OS, since it searches for a zero word in the ROM instead of using one within the POST when trying to communicate with the POST adapter (the zero word must be in ROM).  Fixed to build on non-chrontel STB/NC products.  Lots of duplicate code merged in

MemSize.  MemSize copes better with the softload case, and is less
willing to use the region the OS occupies as video memory, or
page tables.  POST is now ON (memory tests disabled).
OS_ReadSysInfo 4 now uses the NVRAM module to access the ethernet
address in NVRAM/CMOS, so that the availability/location of the
MAC address can be changed.  CMOS location 0 is now unprotected on
STB/NC products to try to stop people poking the hardware directly.
Fixed a CMOS resetting problem on STBs where the value expected in a
location was different from the value written on a CMOS reset, so the
CMOS would be reset every time...

Version 4.69. Tagged as 'Kernel-4_69'

CPU type messages internationalised.
"Unknown OS_PlatformFeatures reason code" internationalised.
RunningOnEmul flag tweaked.
MorrisIDString conditional removed.
New modules added to SWI list at the end of the chain, on grounds that
the first-registered modules are probably more important.
*ChangeDynamicArea moved into UtilityModule from TaskManager.

Version 4.65. Tagged as 'Kernel-4_65'

Bandwidth limit for 7500FE fixed.
RO371Timings flag set to :LNOT:STB

Version 4.64. Tagged as 'Kernel-4_64'

Not fully tested on all hardware permutations.
