I have attempted to install NetBSD onto a dual pentium computer with an
internal scsi interface.

I have tried several different hard drives with the same results.

the installation proceeds normally until it's time to re-boot

after re-booting the screen shows invalid partition table and halts

The pci scsi bios identifies the following devices

PCI SCSI BIOS

ID00 Connor CFP1080S
ID05 Toshiba CD-ROM XM-3601TA
ID06 Archive Viper 150 21531

the connor hard drive is the latest, but I have tried several others with
the same results.

all of the hard drives will format and boot correctly under ms-dos 6.22

I was hoping you might offer a suggestion or two.

PS 

The only reason I am trying to build this machine is to transfer the
Motorola 68K files from the CD-ROM to the tape.

I am trying to install NetBSD onto a Motorola MVME-167 or 177 processor
which won't boot from a CD-ROM
