Some hints:
At the boot prompt of the installer pass the following parameters to the
kernel:
apic noprobe
"noprobe": Installer doesn´t probe for the devices
You have do setup your devices manually. First install the module for the
SCSI-Controller: Use the new Adaptec driver! The old one doesn´t work for
the GX-Boards.
After having installed the SCSI-driver you have to install the
ethernet-device (eepro100-driver).
That´s all.
I´m using a SGI 1200 with RH 7.2 and XFS without any problems. ;-)
