Compaq Deskpro EN 733MHz Pentium III 

>Description:
	The floppy disk generated from floppies/kern.flp is not recognized
	as having a valid MBR unless the BIOS option "Verify MBR" is 
	disabled. Earlier 2.* and 3.* boot.flp disks that I tested worked
	fine. 4.7 and 4.8 both fail.
>How-To-Repeat:
	Get a Deskpro EN and try to boot from a floppy derived from
	kern.flp. It might fail on other Compaq models, too.
>Fix:
	The right fix would be to figure out why the Compaq BIOS is
	rejecting the MBR on that disk, and make it look like a 
	legal MBR. An obvious intermediate fix is to go into Setup
	and disable the "verify MBR" option under "Advanced". But
	I must confess I didn't figure that out until I had ripped
	the machine apart and added a CD ROM dangling by its IDE
	cable to do the actual install.
