[ipxe-devel] No disk found for Windows 7 iscsi install

I'm trying to use iPXE to diskless install Windows 7 Ultimate 32bit to a 
10GB iSCSI disk  (ubuntu 10.10 and IET).  No disks are found by the 
Windows 7 installer.

Target iqn.2011-04.name.jl:w7
	Lun 0 Path=/var/log/iscsi/w7.dd,Type=fileio

Computer:  Dell Latitude D830.  PXE boot gpxelinux.0 for a syslinux menu 
system, then load undionly.0 (ipxe 1.0.0+ - 987b825?)
     (tried directly booting undionly straight from PXE, but that didn't 
make a difference).
     label ipxe-undionly
           kernel undionly.0

Ctrl-B / dhcp / set keep-san 1 set skip-san-boot 1 / sanboot 
iscsi: / exit
     (Registered / Preserving SAN device 0x80)
next boot is Win7 install CD.

Setup log detects iBFT config table:     2011-05-05 08:16:08, Info  IBS 
Callback_BootstrapApplyWpeSettings: Detected iBFT; setup will initialize 
networking support for iSCSI

X:\windows\INF\netb57vx.inf succeeded
IP address received: (as well as an IPv6 address - 
which should be irrelevant).
ping - works.

"No drives were found.  Click load driver to provide a mass storage 
driver for installation".

I've tried with and without a physical HD in the laptop.    I've tried 
with both ATA and AHCI modes on the SATA controller (in case it is 
causing conflicts).
I've also tried with sanhook iscsi instead of sanboot...   None of these 
have worked.

I know that iscsi works in general - because I can boot Windows XP from 
an iscsi disk (sanbootconf/windows iscsi boot drivers), and because the 
drive registers in iPXE sanhook.
I've attached setupact.log.   Any ideas on what I should try next?
