Subject:   FreeBSD/Adaptec 1740 problem

I've been running FreeBSD 2.0 on a Gateway 2000 486SX25 ISA machine with no 
problems for about 2 months. It has an Adaptec 1542CF SCSI host adapter and 
one external 1Gb SCSI HD.

Now, I have problems installing FreeBSD on a Mitac 486DX33 PC with EISA bus. 
It has EISA Adaptec 1740 SCSI host adapter and 2 SCSI hard disks. Under DOS, 
everything worked fine. I decided to get rid of DOS and install FreeBSD. I 
deleted all patitions on the disks using fdisk and started installation. 
When starting the computer, I get a message indicating that both HDs are 
detected:

SCSI ID0 Installed
SCSI ID1 Installed

however, FreeBSD finds only the adapter but not the disks. I tried both 
FreeBSD 2.0-RELEASE and FreeBSD 2.0-950112SNAP. I also tried to set the 
adapter to both standard and enhanced mode (in standard mode it's detected 
as 1540.) I borrowed an Adaptec 1540 (ISA) from my friend, and the disks 
were detected by FreeBSD.

Is that the problem with that particular 1740 adapter or EISA adapters in 
general or I do something wrong? I'm confused and would appreciate any 
help/hints.
