I think it might be! I shan't go into precisely why i think this for the moment (suffice it to say install problems with Woody + boot problems), as i want to confirm or refute my diagnosis. What is the best way to do this?

I was thinking along the lines of something like

install-mbr --list --no-act /dev/hda5

but i'm not certain if this right

It looks like you are trying to rewrite your MBR, the question is what boot manager are you trying to load here, lilo or grub?
Also, do you intend to instal to /dev/hda5 and not /dev/hda

I'd love to help you, but your queston is pretty vague...

Probably, didn't phrase it very well. Here is the question put more simply:

How do i read/display the MBR?

You can take a copy of the mbr by doing
dd if=/dev/hda of=mbr.image count=1 bs=512

How you would view this is beyond me.

I would advise just replacing the MBR  by re-installing GRUB.

In a hex editor. One of the things that is perplexing me is that i've been told my BIOS has LBA support. Woody seems to think otherwise. AFAIK most of the utils (e.g. fdisk, cfdisk etc) cannot tell me if i have an extended CHS partition or an extended LBA partition
