Actually, newer versions of LILO no longer impose this restriction. If the
machine's BIOS handles the extended int 0x13 functions then your kernel can
be located anywhere.

1024cyl * 255 heads * 63 spt * 512 b/s = 7.84GB (assuming 1GB = 2^30 bytes,
not 10^9 bytes as hard disk manufacturers would have you believe because it
makes disks look nearly 10% bigger :) )
