Just for knowledge..
Can I use Intel AHCI ROM in my BIOS of PM55 Chipset with
"Device Description Intel Ibex Peak-M PCH - 6-port SATA AHCI Controller [B-2]
Bus Type PCI
Device ID 8086-3B2F"
?????

@nonid - maybe 1.20E, it may need edited for your chipset though, I am not sure? I'll check in your BIOS, you may already have this, which is best one anyway.

@Fernando, do you know if 1.20E does need device ID edit or OK as is, or do you know from past experience if it is or is not compatible?
I'm going to be unlocking menu attempt for him, so I can look at this when I do that too. Thanks!

Thanks @Fernando, I can edit it, that's what I was asking you about. I have used 1.20E in P35-X58 boards. Were you thinking maybe PM55 wouldn't be similar?

@nonid - I would edit 1.20E, then checksum may need corrected (8-bit to zero or other checksum, and if I remember correctly checksum bit is maybe not the last bit)
If it fails to work, you just wouldn't be able to select or boot to any hard drives, you should still then be able to reflash BIOS from DOS via USB and put back a BIOS without that AHCI module. If you need me to do the edit for you let me know.

@nonid - then it's highly unlikely that inserting an AHCI rom will do anything, nothing will call it to load into functioning. Please link the stock BIOS download, let me look

Thanks @Fernando, I may have been wrong in thinking I've used 1.20E in P35 and P55, but yes I know DeviceID and checksum needs corrected if trying in other boards.
I know, it's getting so old now working on some BIOS that I thought was recent until I have to try and think back to methods used, makes me feel too old sometimes
I don't think he can use though, I thought he was replacing/updating, not blind insertion.

Is it safe to replace Phoenix AHCI Option ROM BIOS 01.05.80 (Biostar P35 motherboard) with Intel 1.20E?

@Horus - I looked at that a few times, not for your particular BIOS I don't think, but last one I looked at the Phoenix AHCI was an ISA ROM not PCI ROM, so I didn't think it would work or at minimal would be ignored and then no disks would be visible.
if you test, let me know outcome, thanks!
