ASUS Intel Beta BIOS Releases and Official Support

[R37ribution]

Thanks for giving me a starting point. I had no idea where to begin. I'll post back my findings here and in the r3e thread once i have some results.
I did test 1502, and it has the same issues that every bios has except 0003, for me... I have to really slack my tWR to get acceptable tRL settings, since I can't set them manually.

I just successfully modded my R3G bios 1003 with Intel RST v10.8.0.1303 (found here) last night and it seems to work fine. Just look for the object with RunLoc 8086:2822 (format is VendorID: DeviceID, in this case it's telling you "Intel":"ICH10D SATA Controller"), highlight it and use the Replace tab in MMTool, DO NOT use delete/insert I've heard it can brick things. For a list of PCI vendor IDs and device IDs goto pcidatabase.com. The problem with the older ROMs, if memory serves me correctly, is that they used an 80KB option ROM and the readily available ROMs were smaller i.e. this updated Intel rom is ~66kb. I use "MMTOOL V3.22 BKMOD" as well, when I downloaded it the file was called MMTool_3.22_Mod_21FiX.rar

Oh and BTW, the worst thing that has happened to me when I installed an incompatible Intel RST/Marvell 9128 option rom was that the BIOS would post and then once it went to load the option rom it would lock up (not to say it can't get worse), so i reset the board to the defaults with the button (intel/marvell roms are disabled) and reflashed. I might have used ALT+F2 I can't remember if that allowed the Orom to load prior to launching the flash utility. Asus boards also have an emergency recovery that can save you if you totally fubar the ROM.

:edit: just checked, you're right the orom in the older BIOS was 51k (80k source) and the newer ROMs are 66k (115 source) so there wasn't enough room.
