Hi!
The first one is allocation error (linuxrc wants to get/read memory, but 
the allocation fails?). The other errors are _maybe_ caused by the first 
error (the scheduler schedules while a atomic operation is in progress). 
Is your Kernel configuration different to the configuration of the 
Fedora Kernel? If so: What did you change?
It's strange that you can't change you Bios settings. Is the write 
protection jumper set to 1 (TRUE/ENABLED)? Is your Bios up2date?
