Try one of Ulrich's pre-installed images instead, and see if the
problem persists.


It could be something rare (RAM or hard drive problem), but for now
I'm assuming otherwise.

Maybe. Which version (5.x? 64-bit? host OS?) are you using? VT-X
enabled? Other relevant settings (e.g. memory managers loaded? HIMEMX
only? JEMMEX?)?

You could maybe file a VBox bug report, but you'd have to give them a
LOT more details. Besides, I don't think DOS is top priority for them
to fix anyways. Honestly, it's probably user error (more likely than
not) than actual bugs, but you never know.

Highly doubtful. What kernel ("ver /r")? Never mind, presumably
whatever came with 1.1 (e.g. 2040).

You could also just use QEMU instead. Some prebuilt Windows binaries
(e.g. 2.5.0) are here:
