Go to http://www.pcjs.org/disks/pcx86/windows/win95/4.00.950/debugger/ . Click Reset and then Run. Notice it hangs. Now, click Halt. Notice the ROM addresses now have zero data values.

For example u f000:c914 on reset, then u f000:c914 when it hangs. Notice the different values.

Yes, it’s a probably a problem with Compaq’s ROM-in-write-protected-RAM feature (or rather, my emulation of it).

yuhong commented 6 years ago

Still a problem.
