Having more than 768MB of RAM makes the screen go blank during a graphical install, forcing me to do a textual install. I've got a Radeon 9500 Pro, which is not recognized by sax2 (it's a brand new card), but trying to configure the graphics as a VESA card using framebuffer gives following error from sax : Could not open /dev/apm_bios (device not found). Similar problem for a GeForce 4 card. Found a solution in Mandrake Forums : use mem=768MB http://www.mandrakeclub.com/modules.php?op=modload&name=Splatt_Forum&file=viewtopic&topic=5576&forum=9 The ati driver (from ATI) is still flaky in 3D mode, though. Cheers Sigfred PS A bit miffed having a kernel denoted 2.4.19-4GB that can't even handle 1GB. This 'Could not open /dev/apm_bios' really threw me off track, thinking it could be bios problems with my motherboard (though Redhat handels it quite well) due to it beeing brand new.
