Having read a recent thread asking people to test the current boot process prior to FC4 test 1 being available I downloaded the latest boot.iso dated 08-Feb 2005 to see if I could get an install to work on my Intel SE7505VB2 based server (on a spare disk as master on the primary ATA channel) only to still get the same result as with FC3 in that you get as far in the boot process as seeing the LOADING sata_sil driver and the system hanging with the message Disabling IRQ #10 being displayed. I gather from reading this list in the past that there is a problem with sata support but had hoped that by FC4 these problems would have been fixed.
