I have an old Pentium PC and it contains leftover peripherals from other PCs:
a. A non-bootable Adaptec SCSI card.
b. A bootable SCSI hard disk with a bootable Linux distro (initrd, grub, ...)
c. A bootable IDE CDROM.
d. A bootable floppy drive.

The SCSI card and SCSI hard disk work.
I know this because I booted a Knoppix Live CD, mounted the SCSI hard disk and was able to read/write it.

In order to just boot the SCSI hard disk, I was wondering if there are any boot floppies out there that will:
* Make the bootup begin from the SCSI hard disk.
* And bypass the "non-bootable" feature of the Adaptec SCSI card.

(I tried SmartBootManager, it cannot boot the SCSI hard disk. SmartBootManager can boot the IDE CDROM.)

Can I boot this SCSI hard disk with "tomsrtbt" ?
If yes, how?

Could try this link:

Hope that helps.

One method would be to use a DOS floppy boot disk using loadlin. The autoexec.bat file would run loadlin which then boots linux. You would add a kernel boot option for the SCSI card parameters. The kernel image would need to fit on the same floppy. This is what I used for my non "bootable" SCSI controller card back in the old days.
