Subject: CWSDPMI re-vectors IRQ0?
Precedence: bulk

After poking around in CWSDPMI and Win95 DPMI at ring 0, I noticed that
Win95, in the IDT, re-vectors hardware interrupts 0-7 to vectors 0x50-0x57
and hardware interrupts 8-F to 0x58-0x5F.  I noticed that CWSDPMI, in the
IDT, leaves IRQ8 at vector 0x70, but IRQ0 is somewhere else besides vector
0x8 (I think).  After poking around in fsdb, it looks like IRQ0 under
CWSDPMI is vectored at 0x88. Is this correct?  Charles?
