What could possibly go wrong? (no, seriously!)

[ptruman]

I've got a GA-Z68X-UD3P-B3 running the latest official *NON* UEFI BIOS, and a very stable Win7 system (Core i5 clocked to 4.4GHz).

Given that I'm running Intel RAID5 with RST, and TPM (which I know I'd have to disable when doing any BIOS upgrade) - is the switch to UEFI likely to cause bother? (i.e. will the RAID5 continue working? Will Windows 7 throw a hissy fit?)

Or is this a serious case of "Backup everything" and "Your mileage may vary"?

Cheers :)

I tried the UEFI BIOS on my Z68XP-UD4. Upon booting, Windows reinstalls all the hardware device drivers. So a RAID 5 array might not even boot. I was only using AHCI and had no problems though.

I would strongly recommend backing up all your data before doing the upgrade.

after you updated to UEFI BIOS, make sure SATA is RAID mode in BIOS menu before boot into OS
