ml350 G1 and external raid

[sander kerkhoff]

i wanted to add some storage space to our ml350 g1 with an ide drive, but apparantly the MB doesn't support ide in udma, so its extremely slow, and unusable

Now i have attotech ul3s uw-scsi card lying around with an external raid tower with 6x160Gb. The UL3S bios recognizes the drive correctly, but i am getting a blinking cursor on the topleft corner when its turned on, and the machine doesn't boot.
What am i doing wrong?
The combo works fine on a recednt winxp machine
