I get the following way... too often when booting from install floppies. I
was able to go through the install once successfully, but now I am getting
the same thing on re-booting from the SCSI disk. Sometimes it does boot
successfully!

Normal kernel boot/config stuff - from the SCSI disk, no problem...then

Waiting 15 seconds for SCSI devices to settle
ahc0:A:6 no active SCB for reconnecting target - issuing BUS DEVICE RESET
SAVED_TCL == 0x60, ARG_1 == 0xff, SEQ_FLAGS = 0x0
(probe0:ahc0:0:6:1): SCB 0x8 - timed out in datain phase. SEQADDR == 0x14f
(probe0:ahc0:0:6:1): BDR message in message buffer
(probe0:ahc0:0:6:1): SCB 0x8 - timed out in datain phase. SEQADDR == 0x14f
(probe0:ahc0:0:6:1): no longer in timeout, status = 34b
ahc0: Issued Channel A Bus Rest. 1SCBs aborted
panic: ahc0: brkadrint, Illegal Host Access at seqaddr = 0x0

then goes into automatic reboot.

This is an old 486DX250, VLB motherboard, 40mb ram, Adaptec 2842 SCSI
controller, no IDE controller, 3COM 3C509 Ethernet. SCSI IDs, 2 = Plextor
CD-ROM, 6 = QUANTUM PD1800S (1.8 gig drive), 7 = host adapter.

This system was running windows NT successfully before I trashed the disk,
DOS boots ok from floppy and has no problems accessing the SCSI devices. I
have low level formatted the drive and ran a bad block and surface scan - no
problems. This system has successfully run Linux in the past.

I am investigating FreeBSD/Apache server for an e-commerce site. So far
Linux looks easier to install.

Any help would be greatly appreciated.
