Like most name-brand systems with on-board IDE, whether there is on-board SCSI
or a freestanding SCSI adapter, the motherboard BIOS in the AP400 will always
boot from an IDE drive if one is present.

Some of the motherboard manufacturers like Asus had BIOS options to allow choice
of boot device. But I think you are out of luck with the AP400.

The system has an Intel 440BX chipset, so its BIOS is probably limited to a max
of 132GB, the same as most systems of this era... Ben Myers

It has the original SCSI drive installed. (About 4 GB)

When I plug in an IDE drive to the "primary" IDE connector it is
recognized. But the machine insists on trying to boot from it.

The boot order feature in the setup program can't seem to distinguish
between the two hard drives although other screens recognize all four
drives correctly (floppy, CD, IDE and SCSI).

Can anybody help me force the box to boot from the SCSI drive?

What is the maximum IDE drive size supported and how can in increase
it?

Thanks in advance....
