I launched a query about this a couple of months ago, but it ran
down without a resolution.
I've got an almost completely stock AST "Manhattan D" fileserver.
It came with WinNT, which I blew up as soon as I got it to write out
the diagnostic and configuration diskettes. I've added a 2GB Conner
Fast/Wide SCSI drive to go along with the IBM Fast/Wide SCSI drive
delivered with the machine. I also added an HP DAT drive.
It's running 2.2.8-STABLE, updated via cvsup approximately once a
month.
The motherboard has an Intel 200MHz Pentium Pro with 256KB of L2
cache, 32MB of RAM and an on-board Adaptec 7880 based Fast/Wide SCSI
controller. There's also an on-board EIDE controller, which is
running the CD-ROM drive (though I think that has no bearing here).
The problem is that the disk drives set up for wide (16 bit)
transfers, but not for fast (20 MHz). The disks run at 10 MHz, and
the tape at 5.
Attached is an edited output of a dmesg, created during a verbose
boot. I left in all disk related messages. I suspect the problem
may have something to do with these lines:
ahc0: Reading SEEPROM...checksum error
ahc0: No SEEPROM available
ahc0: Using left over BIOS settings
Any idea what I should do to get the transfer speed up to speed?
