XP boot failure with Netgear WG511T
Posted by MarkA on May 3rd, 2007


I hope someone has some advice on this:

I have an Acer TravelMate 720TX laptop, running WinXP Home Edition,
Version 2002. The Linksys wireless card just died, so I replaced it with
a Netgear WG511T. All works as it should, except that the computer will
not boot if the WG511T is plugged in. Shortly after the Windows splash
screen appears, I get the BSOD with the message:

DRIVER_IRQL_NOT_LESS_OR_EQUAL

STOP: 0x000000D1 (0xF995F124,0x00000002,0x00000000,0xF994DD49)
NDIS.sys - Address F995F124 base at F9939000, DateStamp 3b7dc561
NDIS.sys - Address F994DD49 base at G9939000, DateStamp 3b7dc561

If I boot the machine with the card unplugged, it boots fine. I can then
insert the card and it works perfectly. I installed the latest driver
from Netgear's web site, but it didn't eliminate the problem.

Any ideas?

Did you completely remove (add/remove programs) the Linksys driver and
its software and reboot before installing the Netgear?

If not, deinstall both cards' drivers and software, reboot, and install
the Netgear driver and software. Then, and only then, insert the Netgear
card the first time.

Actually, I *did* forget to uninstall the Linksys software before
installing the Netgear drivers. However, in the process of digging since
I posted the message, I have found that the copy of NDIS.SYS is a
non-standard size, and has a different date. I suspect it may be a
malware replacement. I cannot delete or rename it from within Windows.
As I type this, I am booting the laptop into Ubuntu, which I will use to
replace the suspect NDIS with a copy of the original, to see if that
helps. I'll let you know how it turns out.

I used the Ubuntu live CD to boot the laptop, and deleted the suspect
NDIS.SYS. I then copied in a replacement NDIS.SYS taken from a different
computer. The laptop now boots without error.
