Hi there,
I 'm setting-up a Pentium P100 gateway (32Mo RAM, 1Go SCSI HD, BT 946-C SCSI 
Card) and I get some problems with my Ethernet Elite SMC Cards.

When I put a single SMC CARD with the following configuration:
IO: 220   IRQ: 10   ADR MAP: D000
all work fine, and with an other one too (IO: 240  IRQ: 15  ADR MAP: 
D4000).
But putting the 2 SMC cards together bring me to the following panic message 
appeared at boot time (Ethernet cards are seen and identified): 
panic: bhacc missing mbif
syncing disks...

So after several tests, and BIOS settings, on different machines (PCI based) 
with different equipment (RAM, HD, net cards, SCSI cards, etc...) I get 
exactly the same results.
Can you tell me what could I do (what settings, changes or whatever) ?

How the PCI<->SCSI card irq can be assigned to 11 (PCI negociation) if I 
exclude this one in the BIOS (used by ISA CARD)!
What could you advice me in the large BT-946C settings (int PIN, BIOS 
related options, etc...)?

Nota:
I succeed configuring my gateway Box with a 486DX2 with VLB Bus (BT-445C 
SCSI Card), so the trouble seems to come from the PCI settings negociation.


Thanks for your help.
