From the page:

<font color=blue size=2 face=Courier New>his error message occurs when the fault handler dispatcher in DOSX.EXE generates another cascaded fault while trying to handle a protected-mode exception. This error is usually caused by one of the following factors:

HIMEM.SYS is unable to control the A20 line.


DOS=HIGH is not functioning properly (related to HIMEM.SYS control).


The RAM, static RAM (SRAM), single in-line memory module (SIMM), or dynamic RAM (DRAM) chips are not functioning properly.


You are running DR DOS.


The third-party memory manager is not configured correctly.


The EMM386.EXE NOEMS x=A000-EFFF line is missing from the Config.sys file.


You have an old, out-of-date ROM BIOS.


Your CMOS settings are incorrect.


Your Windows files are old or corrupted. To test this, create a new directory on the hard drive, and install Windows in that directory.


Your disks are corrupted.


Your system is infected with the Form, Forms, Noint, or Yankee Doodle virus.

Good luck!

Beat me to it, that's what I came up with too...

I come up with the same thing... ;)

Regarding JungleMan's fix, don't necessarily go in order on his suggestions as bad memory will most likely be the fix. Good answer JungleMan.

It isn't a bad CD, it's a hardware problem.

I don't know if this applies here, but i had a similar problem a few weeks ago. This pc had Win2K on it and was working fine till one day it wouldn't boot.I tried everything I could think of, nothing worked. Luckily customer had all his files backed up ( I was stunned! most don't back up a thing), so I tried to re-format and re-install, no go. Then I tried fdisk, format and re-install, still no go. It would hang at different points trying to re-install. I thought I had bad hardware, so I swapped the motherboard and chip( had a known good one in the shop) but still wouldn't re-install win2k. I then assumed hard drive so I went to Western Digitals site to get an RMA number. They make you run their diagnostic software to check the drive and generate an error code before they give you an rma( at least online they do, I know I could have called them and insisted on an exchange )so I ran their software but the drive passed all their tests. As a last ditch effort I tried their " reset the drive to all zereo's" software. I didn't believe it would work, but the drive took off and worked like a charm. I still am not sure why fdisk and re-format didn't solve the problem but the drive is fine now. :eek:

Sounds like bad memory.

Sorry I did'nt get back sooner but the problem was toshiba restore disk is accompanied with a start up disk that configures the config sys.
with DEVICEHIGH=emm386 among other things.
I resolve this issue not with the companion disk but nortons disk doctor?go figure........Had nothing to do with bad memory, just misconfigured memory..

FIX: Kick the POS to the curb and get a DELL.
