Hi:
I'm having trouble booting FreeBSD 2.0.0-SNAP950322, which hangs when it
attempts some tests on my AHA-2940 SCSI card (id 7), BIOS v1.11. I have an
AMD 486-80, a Seagate SCSI drive (id 0), a SCSI Toshiba CD-ROM reader (id 5),
Asus PCI motherboard PVI-486SP3 PCB Rev. 1.2 (or higher), Award Modular BIOS
v4.50G.
I've booted from the floppies on the FreeBSD 2.0 release CD, but since there
isn't a driver for the 2940 in that kernel, the card isn't recognized and
there are no disks to partition with fdisk. However, I have read the
troubleshooting document available there, and turned off extended BIOS
translation for >1GB disks, as well as trying to boot with /kernel -c.
However, the config commands seem to apply only to devices on the ISA bus.
On probing for devices on the PCI bus, these are the messages generated:
Probing for devices on the pci0 bus:
configuration mode 1 allows 32 devices.
pci0:5: vendor=0x1039, device=0x496, class=bridge [not supported]
vga0 <VGA-compatible display device> rev 0 on pci0:10
ahc0 <Adaptec 294x SCSI host adapter> rev 0 int a irq 11 on pci0:12
ahc0: reading board settings
ahc0: 294x Single Channel, SCSI Id=7, aic7870, 16 SCBs
ahc0: Downloading Sequencer Program...Done
ahc0: Probing channel A
ahc0 waiting for scsi devices to settle
ahc0: no active SCB for reconnecting target 15, channel B - issuing ABORT
SAVED_TCL == 0x0
ahc0: ahcintr - referenced scb not valid during seqint 0x71 scb(15)
ahc0: WARNING no command for scb 15 (cmdcmplt)
QOUTCNT == 0
The boot hangs here. The messages prompt a question: why is target 15
being tested? 2940 cards support 8 SCSI IDs, 0 to 7.
Any help would be much appreciated.
thanks,
graham
