[Info-vax] Changed Boot behavior on XP1000 since 2013

[Volker Halle]

Hans,

please try the >>> e toy:2 -w -n 3   SRM commands on your AlphaServer
1200 equivalent system, to see, if they are supported in the version
of SRM firmware you're running. If they work, you should be able to
examine the TOY registers in the same way as on the XP1000 and you
should be able to verify the problem on your system(s).

Once you've verified the problem, it would be time to think about
possible solutions:

- fix the firmware - very unlikely to happen
- add workaround into OpenVMS routine READ_SYSTEM_BBW. Not impossible,
but it's hard to design a workaround in this generic routine for
certain system types.
- patch SYS$CPU_ROUTINE_nnnn of your affected system: something like:
if year > 93 then year=year-80 This routine modifies the year anyway,
as the DALLAS DS1287 chip only keep a 2-digit year and the code has to
add 1900 or 2000. The PATCH utility is available on Alpha, so it's
possible.

Volker.
