I've run into this before on Proliants, and it's usually traceable to a
DMA issue with the CD drive and the installer's kernel.  Try the install
again, but at the "boot:" prompt, use:

	linux ide=nodma

which disables DMA for any IDE device.  That can slow down the hard
drive quite a bit, so it's better to use:

	linux hdx=nodma

In this case, replace "hdx" with one of the following:

	If your CD drive is			Use
	-------------------------------------	----
	Master on primary IDE controller	hda
	Slave on primary IDE controller		hdb
	Master on secondary IDE controller	hdc
	Slave on secondary IDE controller	hdd

So, using a normal system where the CD is the master on the secondary
IDE, "linux hdc=nodma".  This would disable DMA on the CD drive only,
rather than the whole bus.
