Jim,
would you care to explain why this isn't a bug and why is it correct,
please? Because I don't get it as well and I'd like to know.
I sat down, I did binary/hex/whatever thing and came up with the
following values for '&' . Order of the values is as in IPMI spec PDF
p. 391:
* 0xEF - OEM
* 0xF7 - SMS
* 0xFB - OS
* 0xFD - Loader
* 0xFE - BIOS
Ok, may be I'm going to make an ass out of myself, but even that's a
way how to learn and improve.
Let's take ``OEM has handled boot info'' case which, I think, is
'11101111' in binary. And when you '&' this value with 0x10, which, I
believe, is '00010000' in binary, don't you get '0' out of such
operation?

11101111
& 00010000

00000000

It has been long since high school and I don't practically use this,
so it's possible I'm just wrong. It's even possible the code in
question works differently, data structure has completely different
values and it all makes sense. I have no way how to toy with this in
ipmitool, otherwise I would and wouldn't be asking questions.
Yeah, it seems to me these conditions are incorrect.
And Jim, if you don't know the answers, please, let me know and I'll
put more time into it. More than spec, pencil, paper and reading
through small and isolated portion of the code. No problems.
Thank you for explanation and patience,
Z.
