Trying (and failing) to boot LFS from a Compact Flash card

thanks for the info, I just added rootdelay=8 to my kernel parameters and 
that fixed the problem. My USB stick is slightly faster, but not much. I 
noticed that there are a lot of BIOSes that do not allow booting from USB 
devices :-(. Guess I'll be needing a bootdisk to go with it now.
