Okay I understand more of your problem in Ubuntu now...
If you use lp in Linux or copy ... prn in dosemu, the
latter will basically assume that you want to print a
plain text document. Lp might also support postscript

I pretty much agree. I actually don't really need or even want access to even
the full 4GB that a 32-bit CPU allows, but would like what's there to work
correctly no matter how much memory there actually is. My newest computer came
with 6GB (64-bit Vista), which I multi-boot to DOS. I had to

Yes, the IRQ is normally set automatically, either by the BIOS or by
USBUHCI{L}. The reason JVP needed to change it was beca

If you run cwsdpmi like that, it will probably not
stay in RAM? Apps made with FreeBASIC will just load
cwsdpmi themselves while
