RW has been causing problems for lots of folks, myself included.
Basically, I've stopped using it.
If you want to try to get it working, be sure RW is set up to use "wav" recording. Direct Sound recording seems to cause many problems.
Video bios cacheable or shadow is something you find in your BIOS setup. Press F-10 usually, or something like that to get into your BIOS setup. Poke around in the different menus and you may find it. If video cacheing or shadowing is enabled, you should disable it.
