We had a similar setup on some IBM think centres a while back. If using a floppy boot image.
The crucial bit is: You need to create a < 8mb FAT12 primary partition on the hard disk. This partition needs to be bootable.
Next dd the .lzdsk file into the partition. dd if=BOOTROM_IMAGE.lzdsk of=/dev/hda1
We used grub to choose whether to boot this partition but there's no reason it shouldn't boot directly.


Hope that helps

dear all,

for the record, i tried your suggestion of:
     #dd if=/dev/*.zdsk of=/dev/hdb

this on a hd with no partitions. it did not work.

then, also created a small partition made active, and tried:
     #dd if=/dev/*.zdsk of=/dev/hdb1

did not work.
in both cases the error is the same, the hex code that shows the pc has
found nothing on the hardisk to boot.

so here's the brute-force fix that works, but it is not the solution:

took the hardisk, that boots an ltsp workstation and cloned it to the
second hardisk.
     #dd if=/dev/hdb of=/dev/hdc

this works, but i still don't know how or why.
so for the moment, the client is happy as his workstations are gonna get
converted to ltsp workstations.

for the record, about that original, working hardisk.
a few months ago, i was trying the same objective, (boot an ltsp
workstation from a hardisk, as if it's a boot floppy).
during my experiments, had also tried a lilo boot on it. so it still has
a 500mb RH8 install, with an additional unformatted 3.5gb.
when the pc boots, it shows no lilo or grub, and immediately boots via
ltsp.
