You might try updating to a more recent dev release of opensolaris.
There were several fixes since 117 that were motivated by issues with
gPXE boot. I don't recall right now whether or not we ever received
confirmation that gPXE boot now works or not. You may also wish to
upgrade to a more recent version of gPXE. I know that code base is
also under active development.

I have 2 desktops that were running diskless booting from iSCSI (gpxe). One is 32 bit the other 64 bit.
After converting from iscsitgt (shareiscsi propery) on snv 117, one of the
windows hosts cannot boot from iSCSI.
- 32 bit XP - everything works fine
- 64 bit XP - starts booting, but when it's just about to switch to login
screen hangs for about 40 seconds then comes up with Blue Screen that it cannot
read SAM or SYSTEM registry (different messages).
Reverting to siscsitgt allows windows to boot normally. Once booted, i can
attach and mount devices from COMSTAR, but not boot from them.
Any ideas on how to troubleshoot this?
The performance difference is amazing. I am getting 16'000 random 4K IO/sec
over gigabit network (from memory) and this maxes out the dual-core CPU on the
server.
Compared to 7'000 with iscsiadm.
Latency (with queue=1) drops from ~0.5 ms to ~0.24 ms (4K)
