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
