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? -crl -- Chad R.
