I have 2 new boxes that I cannot use yet because of problems supporting these newer chipsets in 5.1. Does anyone know when the CD version of 5.0 x86-64 that has support for these chipsets be available on any on a Centos mirror? Has the support for these chipsets been added to yum yet? Here are my latest results with these chipsets and Centos 5.1 1. Asus P5K, E6850, P35 Chipset: Does not boot or install without "acpi=off all-generic-ide irqpoll nommconf" Also, when it does boot it does not recognize LAN and video hangs loading gnome. I tried install the Asus Linux driver for the mobo but 'make install' produces error that kernel sources cannot be found. 2. Asus P5K-VM, Q6600, G33 chipset: Installs and boots as long as "acpi=off" switch used. But I understand this disables multi-core support. LAN and video are working. thx -- Mike __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
