It says "Abort on data transfer".

Detail:
  Added the HAL NVRAM entries.
  Modified i2cutils to use the HAL entries for NVRAM and behave sensibly if the HAL reports that there is no NVRAM, in which case there must be a forced reset_cmos call so that the cache gets set up sensibly.
Admin:
  Tested under the RPC emulator and appears to be working correctly, although some calls to IIC are still being made in the no nvram case.

Version 5.35, 4.79.2.5. Tagged as 'Kernel-5_35-4_79_2_5'

Version 5.35, 4.79.2.2. Tagged as 'Kernel-5_35-4_79_2_2'

* Added ARM_IMB and ARM_IMBRange SWIs as recommended by ARMv5.
* Some early prototype HAL bits popped in - a lot of source restructuring still
  to come.
* New debug target creates an AIF image with debug information, and translates
  this into an ASCII object file for the 16702B logic analyser.

Version 5.35, 4.79.2.1. Tagged as 'Kernel-5_35-4_79_2_1'

  Added common error cache.
Detail:
  Fixed module header validation code which was broken in 5.22.  This
    shouldn't have caused much of a problem as it was only a bizarre
    check (SWI chunk looked valid but SWI handler was 0) that would
    have failed - but be reported as a valid set of SWI entries.
  Added common error message cache.  Several common errors (Buffer
    overflow; Number not recognised; Bad vector release; and a couple
    of others) are now cached the first time they are translated into
    a block of memory in the system heap.
Admin:
  Tested in Ursula build - cacheing only active in Ursula build - change
    HdrSrc if you want it in your products too.
  Requires HdrSrc 0.94

Version 5.31. Tagged as 'Kernel-5_31'

Detail:

  * Lazarus builds of the Kernel failed with the following error:

      Immediate value out of range at line 458 in file "s.NewReset"
              ADR    R2, IRQ_Test_CTRL_or_R_Pressed

    This is due to the ADR going out of range.  Changed to use ADDR
    macro instead to rectify this.

Admin:

  * Untested at time of check-in; to be verified in next Lazarus development
    build.

Version 5.25. Tagged as 'Kernel-5_25'

  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'

Power down A to D convertors on reset.

Version 5.05. Tagged as 'Kernel-5_05'

Right arrow on a remote also acts as Delete.

Version 4.98. Tagged as 'Kernel-4_98'

* Wasn't allowing writes to most of EEPROM.
* Old prototype OS_SetTime SWI code removed.
* MPEGPoduleNTSCNotPALMask option support removed to simplify things a bit.
* Now can cope with a system with a PAL/NTSC link, but no monitor detect line.
* Default PAL & NTSC modes now always 12 & 46 respectively.
* Kernel now knows about monitor type 8 (NTSC) - modes 44-46 (640x200) are
  available.
* STB/NC CMOS test removed from POST pending further investigation.

Version 4.90. Tagged as 'Kernel-4_90'

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'

ObsoleteNC1CMOS (like the CMOS header file).

Version 4.71. Tagged as 'Kernel-4_71'

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'

RISC OS 3.7 generation kernel).
CMOS no longer gets scrambled when reset in STB build.
UpCall_KeyboardStatus now issued when OS_Byte 202 called or when keyboard
status byte is changed by other means (such as pressing Caps Lock).

Version 4.67. Tagged as 'Kernel-4_67'

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.
