Subject:   timeouts with adaptec 1742

I have been trying to get a Seagate ST32151N (Hawk 2-XL 2GB) to
work with an adaptec 1742. During the install at the commit step, the
system hangs (the activity LED on the adaptec remains on) and after
about 15sec. The message "Panic(adaptec 1742) for historical reasons" is
displayed. After another short delay, the system reboots.

The drive works fine (in the same system) using DOS 6.22 and
Windows 3.1. Initially, I had timeout problems there as well,
but after downloading the latest eisa configuriation files from adaptec
the problem went away. These configuration files allowed me
to set a specific IRQ (11) and to specify  edge trigerring.

I have installed FreeBSD on another disk and tried to label the
ST32151N under FreeBSD. I can usually fdisk and disklabel it,
but when I try to create a file system, the timeout occurs and
the system panics. The problem is similar if I run the card as
a 1542 and use the aha driver.

Using EZ-SCSI I found that the drive doesnot support
SCSI-Linking (?) while the older drive does. I am not sure
if this is pertinent but I thought it might be useful.
I have been struggling with this for about 3 weeks.
Any help would be appreciated.
