I need to run Seagate diagnostics utility (Seatools), but my computer has no cd reader, no floppy drive, and my disk is so defective that grub won’t boot.
But it has a NIC that supports PXE.
Enter the BIOS, enable network boot.
Boot, write down the mac address.
On another computer (currently a debian squeeze), install a dhcp, pxe, a tftp server and gpxelinux (see the second link above, in french).
Download « Seatools for DOS », it’s an iso image. Rename it to seatools.iso and save it in /srv/tftp
Edit /srv/tftp/pxelinux.cfg/default and create an entry like:
label 1 MENU LABEL Seatools kernel memdisk append iso initrd /seatools.iso
And voilà ! You can now boot this iso image via pxe.
