The problem in one word: SCSI.

Your machine has SCSI boot support in its BIOS, so the boot loader is able to load. But the boot loader itself doesn't have support for your SCSI adapter, so it can't load the kernel. Even if the kernel were loaded, it probably wouldn't have support for the SCSI adapter built-in, though your distribution might have a pre-boot RAMdisk with the appropriate driver in it. (I haven't tried Mandrake, so I couldn't say.)

You will probably have to use floppies to install on that machine, or scrounge up an IDE CD-ROM drive.
