iPXE, iSCSI and int13

[mr_jrt]

Had another poke at this this evening.

Figuring that until I figure out how to control XP setup's disk ordering I needed to remove my USB stick from the equation, I built an iPXE floppy image and copied the image from my iPXE boot CD to it so I could boot from a floppy and then install XP from the optical drive - no USB HDD needed.

As suspected, it was successful - XP text mode completed correctly. However setup stage 2 will not start - NTLDR states that it cannot open the iSCSI target:

Code:

Couldn't open drive multi(0)disk(0)rdisk(0)partition(1)
NTLDR: Couldn't open drive multi(0)disk(0)rdisk(0)partition(1)

I've tried specifying the --keep option to sanboot, but it doesn't seem to do anything:

Code:

iPXE>dhcp
Configuring (net0 <mac>)....ok
iPXE>sanboot --keep iscsi:<spec>
Registered SAN device 0x80
Booting from SAN device 0x80

<NTLDR errors>

...so it's clearly returning the bootloader.

I appreciate this isn't the place to ask for help booting XP over a SAN (and I will ask elsewhere), but if there's anything relevant to iPXe it would be appreciated.

The instructions I've been looking at are found at:

..both of which suggest it should probably just work.
