Re: Multi-kernel in grub

[Travis Osterman <travis@wsor.net>]

To eliminate another variable, I tried to run the kernel compilation
without changing any kernel settings (just to see if the kernel source
would compile).

Without any configuration changes at all:
# make mrproper		// no errors
# make clean		// no errors
# make xconfig		// no errors
# make dep		// no errors
# make bzImage		// below (seems fine)

tools/build -b bbootsect bsetup compressed/bvmlinux.out CURRENT >
bzImage
Root device is (8, 7)
Boot sector 512 bytes.
Setup is 2621 bytes.
System is 1156 kB
warning: kernel is too big for standalone boot from floppy
make[1]: Leaving directory `/usr/src/linux-2.4.20-8/arch/i386/boot'

# make modules		// no errors
# make install		// below

Thanks again for all your help in sorting through this with me.
