Maybe safer: dd of=/dev/sda if=/dev/zero bs=512 count=1 As far as I know, the core part of the MBR is only 512 bytes. There _is_ some free space afterwards (not sure how much), where things like GRUB can store some of their boot code. BTW - you _will_ destroy the partion table with this. The partitions shouldn't be touched though, so if you wanted (?) you could re-create them manually as long as you know the exact layout. Yan

So initially it will not have an mbr and install from lan. Afterwards it will pick up the harddisk installation.
If you need to reinstall just(!) wipe the MBR:
dd of=/dev/sda if=/dev/zero bs=1024 count=1
(no guarantees on that one - don't complain if you wipe your whole disk)

Has anyone done a network install of SUSE when the client is started with wake-on-lan? Is this even possible?
The reason I ask is I am unsure how you disable a machine from being installed each time it boots. Do you have to turn on/off PXE (or whatever you're using) in the BIOS when you want to change behavior? Or modify the dhcp server's setup? I guess either would work. What are people doing in practice?
