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. >Release-Note: >Audit-Trail: From: "Ted Mittelstaedt" To: , Cc: Subject: Re: i386/50887: MBR on kern.flp fails Compaq MBR validation on 4.5+ Date: Sat, 13 Sep 2003 08:18:49 -0700 What version of Compaq BIOS does it have?
