I wanted to try playing with Xen, so I built a Xen kernel, but Lilo won't
install it, claiming that it is "too big". I think the problem is the
/boot/vmlinux-syms-<version> file (since the /boot/vmlinuz-...xen....
file is no larger than other kernels). I also read something that
indicated Xen does not work with LiLo.

So I decided to try Grub. When I run grub-install:
grub-install --no-floppy /dev/hda
It just sits there. Apparently doing nothing.

Dmesg reveals:
Buffer I/O error on device fd0, logical block 0
end_request: I/O error, dev fd0, sector 0
end_request: I/O error, dev fd0, sector 0
end_request: I/O error, dev fd0, sector 0
Buffer I/O error on device fd0, logical block 0

Buffer I/O error on device fd0, logical block 0
end_request: I/O error, dev fd0, sector 0
end_request: I/O error, dev fd0, sector 0

This, despite:
1. Using the --no-floppy switch.
2. The lack of a floppy drive in my system.

How can I solve this problem?
