I'm not using the onboard NIC because the 1.0.1 version of gPXE that I
downloaded from ROM-o-Matic didn’t recognise it. The network card I’m
using is a 3Com 3C905C-TXM PCI card.

The Windows 7 installer doesn't even show the disk as a target to
install to, although my iSCSI server shows that the initiator is

No I don't think I've seen "SRLBCG" printed.

I’m using tgt installed on CentOS though I’ve also tried iscsitarget on ubuntu.

This results in a blinking cursor as described in my original email.
I’ve tried using lun 0 using iscsitarget but that doesn’t make a
difference. For some reason tgt doesn’t let me use lun 0.
When installing Windows 7 I use these commands (note: I followed Matt’s
advice and added the initiator name line):
set keep-san 1
set initiator-iqn INITIATORNAME
As described before, the Windows 7 installer doesn’t display the disk.

Just the onboard NIC and a PCI card. I can try a different one if you
think that would help? Would any of the other hardware cause an issue?
Or is it just the NIC that matters?
Thanks for your help!
