Do not despair. Rescue is on the way :-).
Actually, I disassembled the mini400i.sys driver, and found the
magic incantation which enables the HP-card and maps it into the
IO-space.
The mapping seems to work just fine. The only part I'm still struggling
with is the fact that the NCR5380.c driver apears to be *hopelessly* non-SMP
safe (and I happen to be running an SMP box).
In case anyone cares (I'll be including this in an official patch
later, which also fixes the SMP-compliance, I hope), this is what the
HP card needs to get mapped at port 0x280:
/* wakeup sequence for the HP-NCR53C400A */
outb(0x0f, 0x779);
outb(0x22, 0x379);
outb(0xf0, 0x379);
outb(0x20, 0x379);
outb(0x80, 0x379);
outb(0x80, 0x379);
No need to boot from DOS anymore.
