<tt>I think that you meant to type "BIOS drive 0x80" rather than
"drive number 0". BIOS drive 0x00 would be the first floppy disk
drive.</tt><br>

<br>
<tt>If you wish to change the drive number away from 0x80, what are
you hoping to do with it? Boot it? I am under the impression
that a lot of HDD boot-loader code expects to be run from drive
0x80.</tt><br>
<br>
<tt>gPXE assigns a "natural" drive number to the SAN; the "natural"
number would be the next number available. If you had 0x80 and
0x81 already, then it would get 0x82. But then gPXE swaps that
with the real 0x80 just for booting purposes, since 0x80 is
traditionally the booting HDD. See
gpxe/src/arch/i386/interface/pcbios/int13.c for some relevant
source code.</tt><br>
