Hello, I just succesfully flashed my P5Q Deluxe with p5qd3201m.rom (2097152 bytes) Beta mBIOS

it's the one with theses changes:
- Replace memory table with P5Q Pro Turbo 602 table
- Update Intel RST O-ROM to v11.2.0.1527
- Replace P6 table with P6 table from P5Q Premium 2406
- Update JMicron to v1.07.28
- Update Marvell 88SE6121 to v1.1.0.L73
- Update Marvell Yukon to v6.6.2.3

I'm running it succesfully with 4x 1TB Samsung Spinpoint in AHCI mode.


btw, somewhere on the internet I've found P5Q Deluxe EFI Bioses (revision 0221)
moded with Intel RAID ROM 10.1.0.1008 and 11.0.0.1339
filenames are:
ASUS_P5Q_Deluxe_0221_IR10.1.0.1008_OROM_MOD.rar
ASUS_P5Q_Deluxe_0221_IR11.0.0.1339_OROM_MOD.rar
you can just google em
If anyone has experience running P5Q Deluxe with EFI "bios" (or moding EFI bios), plese post your experience
