Thanks for the response but it's not the answer to the question I was looking for. I wanted to know how I could wipeout enough of the bootblock to cause PXE Boot to occurr without damaging the partition table. I'm not asking about how to partition in the %pre section. We are already doing this because we need to bypass anaconda's partition and formatting routines to support filesystems that are not supported by RedHat 7.1. -----Original Message----- From: John [mailto:red@xxxxxxxxxxxxxxxxxxxxxxx] Sent: Thursday, June 19, 2003 4:27 PM Cc: 'kickstart-list@xxxxxxxxxx'; anaconda-devel-list@xxxxxxxxxx Subject: RE: restore boot block On Thu, 19 Jun 2003, Fong Vang wrote: Do not reply directly to me. _I_ read the list, and one copy is quite enough. > I tried wiping the first 446 bytes and bytes 511-512 with these commands: > > dd if=/dev/zero of=/dev/hda bs=446 count=1 > dd if=/dev/zero of=/dev/hda bs=1 skip=510 count=2 > > I then did a reboot and PXE boot did not occur as expected.

It's true I'm not using kickstart, but this can be done in %pre - it's the first place I ever tried it. I've not read this thread at all closely (I tend to ignore q's asked in more than one place), and I've long forgotten what PXE has to do with it. However, this _does_ clobber the partion table and make the disk unbootable (which is why I have the dd there), and it does leave me with a valid partition table (constructed just the way I want it), still unbootable until I get round to installing grub a few minutes later. export BootPartition=25 RootPartition='' function partition_disks() { #fdisk -l /dev/hda dd if=/dev/zero count=1 of=/dev/hda fdisk /dev/hda <<. d 1 d 2 d 3 d 4 n p 1 1 +${BootPartition}M n p 2 ${RootPartition} p w This e-mail has been captured and archived by the ZANTAZ Digital Safe(tm) service.
