I have an application that won't run in a dos box under win2k. The HD

do this.
They do? I haven't seen such a feature. I've seen mention of it for the
Mac side, but I didn't know something like that was possible in Windows.
It makes sense on the Mac side since there's built in support for this
sort of functionality.
Ghost even gives the option to add files to the ramdisk before the
reboot. But it's cumbersome and there are licensing issues if I want to
do this on multiple machines.
Unless I'm missing some big piece of this puzzle, to do something like
this, you're going to need to alloc physical RAM, and somehow either
instruct the BIOS to boot off of it, or do some fiddling with the boot
loader to load a ram driver and launch your RAM drive wherever it's been
loaded into memory.
In other words, not something for the faint of heart, and not something
I think you'll find sample code to do, much less code in VB to do.
If I had to do this, I'd look into using something like GRUB to do the
booting for me, and see if there's any way I could point GRUB to use a
configuration file on a FAT drive that can be easily changed as needed
by either the DOS or Win2K side of things.
