      OS_ReadSysInfo 2 now reports whether the IIC bus is fast (in bit 24 of R2), and whether I/O clocks should be stopped when idling the processor (bit 25).

OS_Byte 19 is a bit more careful in its use of Portable_Idle - an edge case
where the vsync interrupt was already pending now returns immediately.

      * Meaning of FEIOSpeedHalf was accidentally inverted. · fb297c9b
      Kevin Bracey authored 
      * 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.

      Default RCLK mode now RCLK/2 rather than RCLK/1. · b28fe2e3
      Kevin Bracey authored 
      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).

      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...

      Kevin Bracey authored 
      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).
