feline, technically, I'm only really using 2 OS's, XP and QNX. It's just that QNX was installed into the 'partition image file' created by VMWare as a Win98 'machine'.
Normally QNX cannot install into NTFS, and Win98 either, but both are happy on the same 'C' drive as the Host XP.
QNX boots via a floppy accessed as the Win98 machine 'posts'....
One of the fun things is having LiteSTEP running twice, once in each system, and Windowblinds, too.
The only 'strange' part is when you have WinAMP playing in XP, and WinAMP playing in Win98....at the same time, both accessing the same soundcard....
"Row, row, row your boat....
Row, row, row, your boat...
Jently down the stream...."
THAT's when it gets weird...
