This is how to install Windows Vista on the PS3 with Qemu 0.9.1 BiOS Rev 1.171. It's a 100% PS3-based emulation of Microsoft Windows Vista... super slow, but it works. :p

1. Install/Download Qemu 0.9.1 (Redirection)
2. Download Bochs Bios Rev 1.171 (SourceForge.net Repository - [bochs] Log of /bochs/bios/BIOS-bochs-latest)
3. Install Vista on your Computer using Qemu and Bochs Bios Rev 1.171.
4. Vlite helps speed the install up, Vista's install make take a day or so.
5. You may also need to add this command "-cpu pentium3" for Qemu to work right.
6. Copy the .IMG to your PS3's HDD
7. Open Terminal where the Vista IMG is located
8. Type:
Code:
qemu -hda vista.img -m 256 -L "Location to Rev 1.171, Drag n Drop" -cpu pentium3
(The -cpu pentium3 option makes it so it doesn't BSOD with error code 7F)

It will take about 25 min to fully boot (network connection and audio show up).
