Thanks for explaining the "root" cause of my problem - ICH8 support only happens AFTER installation, but is needed IMMEDIATELY to even get to the install screen.
IF someone could make an Install DVD with ICH8 support from the get go you could probably pop in the disc and install just fine (when booting form a USB connected DVD-ROM drive, that is).
I got the bright idea to make a dd image of a CLEAN/PATCHED OS X 10.4.8 w/8.8.1 kernel to make a linux based install DVD to act as a XPS410 restore disc of sorts.
Also, I don't think the Sound or LAN will ever work on the XPS 410.
I haven't had any problems booting off directly off my SATA DVD, I just can't get as far as the GUI install screen, because of "waiting for root device".
The disk image copying method would be cool (or even a vmware image with the ICH8 patch maybe?), but ideally a bootable DVD with the native ICH8 support would be best.
thanks again, but without LAN support it's sounding pointless for my work office needs (vmware would do though).
