And then there's my 946C which still insists as showing up as an ISA
device. The card is in a PCI master slot, the slot's enabled under
CMOS with mastering=enabled. Under AutoSCSI, it says it's at 334. I
can't find anyplace in AutoSCSI that refers to `1540 compatibility
mode' or `ISA mode' except ISA DRQ compatiblity setting, which I've
got set to `None'. Nowhere in the docs does it mention port address
like e800---330, 334, 230, 234, 130, and 134 are the only ones I could
find.
JP4 and JP5 are both jumpered, if that matters. The card isn't
detected at all if I remove both jumpers---at least one has to be in
place.
I tried booting with -c and setting the I/O port to e800, but the
kernel always reports `bt0 not found at e800'. At least I get sync
mode.
Any ideas?
