Summary:  Tulip/2114X NIC netboot causes win2k lockup on boot

Original Submission:  Set up grub with --enable-tulip; loaded boot sector for 
win2k over tftp and chainbooted to it. As windows loads, it locks up as it 
tries to initialize its devices (progress bar about half way). Reproduced on 
different machines and slightly different NIC revisions. My guess is that the 
crappy windows driver is expecting the NIC to be in power-up state, but since 
grub has used the NIC, it confuses the windows driver and locks. Problem was 
resolved when I used a different chipset NIC. Perhaps reset the NIC or PCI bus 
or something just before booting to make sure the cards are in a power-up-like 
state that an OS or driver might expect?
