Kernel Panic: VFS:

Does the fact that I have a 1048 sector harddrive have anything to do with my kernel not booting up after I have completed compiling and running zdisk on it?

Probably does...

Try turning on LBA translation mode for that drive in your PC's CMOS setup.  Hard disks with > 1024 cylinders can mess with boot loaders.

Failing that-- your boot disk might think its root filesystem is going to be somewhere other than it actually is.  Boot "happy" (from a disk that works, get your hard disk mounted on /) and type mount.  The drive mounted on / should be the root device of your boot kernel.

To see what the root device of your boot kernel is going to be (well, hey, let's make our own boot disk while we're at it)-- after doing a make zImage, do:

cd /usr/src/linux/arch/i386/boot
rdev zImage

It should show its root device as the same as what's mounted on /.  If not, do:

rdev zImage /dev/hda3

or whatever the device for your hard disk partition is.  Then, to make a bootkernel disk from the zImage, do this with a blank low-level formatted floppy in the drive:

dd if=zImage of=/dev/fd0

Once the floppy stops churning, try booting off it.  If none of this works, get back to me.
