I recently had to setup Fedora 16 to test something on a SuperMicro 6015T-TV 1U “dual” server. This is a 1U enclosure with two separate servers in it - based on the SuperMicro X7DBT motherboards - each with an AOC-SIMSO+ IPMI and KVM-over-IP management card. Every time I tried different options for the kernel parameters (I was using Cobbler), I could get the OS to boot, but once Anaconda started, I’d lose image (“No Signal”) on the IP KVM, and the serial console would go quiet. It took me about a dozen tries before I found a mailing list reference to the “nomodeset” option. This did the trick perfectly, and kept Anaconda working.
