Hello all,
I've just installed FreeBSD 2.0 and it's simply
marvellous. Congrats to everybody involved.
However, I have the following problem.
I have an Adaptec 1542 SCSI adapter with an external
1GB disk and external quad-speed CD-ROM. I also
have a WD1007V internal disk. I wanted to install
FreeBSD on the SCSI disk only. The problem I ran into
was if I enabled the SCSI BIOS, then FreeBSD couldn't
talk to the adapter (see messages below). Without the
BIOS enabled, I can't use the SCSI disk as a boot disk.
The interim solution I've chosen is to install the root
partition on the WD1007V and everything else on the
SCSI disk. While this works fine, it means I can't install
the SCSI components in another PC and boot FreeBSD
because I don't have a root partition.
Is there any way to install solely onto the SCSI disk? The
FAQs indicate that this should be no problem once you
specify "hd(1,a)kernel" at the boot prompt.
The error messages I got from FreeBSD when the BIOS
was enabled are as follows:
aha0: reading board settings, dma=5 int=11 (bus speed defaulted)
aha0: aha_cmd, cmd/data port full
aha0 at 0x330-0x333 irq 11 drq 5 on isa
aha0 waiting for scsi devices to settle
probe0(aha0:0:0): timed out
adapter not taking commands... frozen?
Debugger ("aha1542") called
/* The last three messages are repeated here */
aha0: MBO not free
Does anyone know what the problem is? Please note that
the exact same problem occurred on a Gateway 2000
Pentium with an internal 1GB disk.
The 1542 is of recent production (chips labelled 1995). It
has what I'd call a SCSI-2 connector for the external
devices. The CD-ROM is a SCSI-2 device. I'm not sure
about the disk.
I know this isn't conclusive, but everything works fine
under DOS (although I'm not booting from the SCSI disk
under DOS, the devices are at least accessible).
By the way, I've done the usual things like take out every
other card (except the VGA card) and I've tried various
other IOMEM and PORT values, to no avail.
Any help really appreciated.
Mike
