Aopen DE-945 CD (reported as i945GMx-BCD/CD R1.04)
BIOS version R1.04

I've re-flashed this BIOS to my MB but it will not save settings to CMOS. Basically, all I need is for it to stay in AHCI mode but still be able to go back to IDE if needed. I've checked/removed the battery to no avail, sometimes it will save for a couple reboots but often won't save settings at all.

I've made edits in Modbin6 only to the AHCI setting and tried flashing with the EzWinFlash bundled with the latest official BIOS and Phoenix Winphlash 1.7.16 (and earlier variations) but have come up with error codes. OS is WinXP.

Any help or pointers would be great. Are there any other Phoenix flashers out there aside from Wflash which I've read horror stories about?
