I had lilo set for:

        alias=4

Are you using the raid-extra-boot option?  If you aren't you probably
want to be - it'll allow the system to boot if one of the boot drives is
dead.

However, this shouldn't be preventing you from mounting root.

When I installed 2.4.18, all of a sudden I can't boot, EXT2-fs: unable
to read superblock. Yes, I selected all the RAID options on kernel
compile.

This may sound dumb, but are you sure you didn't compile RAID1 as a
module?  If you did, you'll need to use an initrd to load the module
before you mount root.  Otherwise, you'll need to rebuild the kernel
with the driver included in the kernel.
