I tested this item in Windows XP. The largest value that works over this 
USB-NIC (in windows xp) is "-s 1472".

Yes, I used the latest version of sanbootconf.

After using the Windows XP image made from USB flash drive, I can 
successfully sanboot Windows XP via this USB-NIC. Since this USB-NIC only 
fits to USB 1.1, booting speed is extremely slow (took about 5 minutes from 
power on to windows xp operable).

Because the driver of this USB-NIC and PXE support is loaded from FDD ( it 
took more than 1 minutes to load driver and PXE), I tried to load iPXE 
directly from the USB flash drive. When I did this, iPXE seemed can't find 
the USB-NIC.

What should I do to make the USB-NIC workable while the iPXE is loaded from 
USB flash drive? Thanks very much!

Regards,
Jerry
