Very Computer

I'm trying to install 3rd and 4th Maxtor 7420AV IDE drives on my Acer
Altos 700i server.

This machine uses Saturn Rev 4 PCI, and has a CMD 640A (rev 1)
controller on the motherboard, controlling 2 EIDE ports.

The drives work fine if installed as 1&2, and are identical to the
existing drives 1&2.

autoprobing works fine, correctly identifying the drive type,
cyl,hd,sec and that ide1 is on irq 15

If drives 3&4 are plugged in, the boot sequence never completes,
failing with the following messages.

hdc: set_geometry_intr: status=0xd0 { busy }
ide1: do_ide_reset:sucess
hdc: set_geometry_intr: status=0xd0 { busy }
ide1: do_ide_reset:sucess
hdc: set_geometry_intr: status=0xd0 { busy }
end_request: I/O error, dev 1600, sector 0

hdc is major 22, minor 0
hdd is major 22, minor 64

About the only strange thing is that the machine's bios only reports 2
drives. (Acer bios)

If drives 3&4 are not plugged in, ide1 is not detected.

Any thoughts would be much appreciated...

Anyone got any better suggestions?
