Re: kernel boot problems

[Andre Hedrick <andre@linux-ide.org>]

Maybe try enabling ATA/IDE driver as the configuration at compile time has
changed.  Using an old 2.2 '.config' will fail to enable the subsystem.
However using a 2.4'.config' on a 2.2 compile will generally succeed in
90% of the flags.

Cheers,
