OK, now that I have read this thread a lot more carefully, I think I have a few questions.

There is also an AHCI option rom, is there any chance i can update this as well? 

 
Are you talking about the Intel AHCI Option ROM 1.20E? If so, we have tried to integrate this into our BIOS before, but never with 100% success. Unfortunately, the EVGA X58 BIOS uses a Phoenix AHCI ROM, which is unique to Award-based legacy (non-UEFI) BIOSes. That being said, it is possible to replace it with the one from Intel, but after doing so, setting the BIOS to AHCI instead of IDE or RAID will then fail to detect any hard drives or optical drives. The workaround is to simply set the BIOS to RAID. This will still let you use single or multiple hard drives as stand-alones (not in a RAID array). Doing this will basically not invoke the AHCI ROM at all, which shaves off a couple of seconds of boot time. 
I am currently using a modified version of my BIOS posted here with the addition of the latest available Intel AHCI ROM 1.20E0027 as well as the latest Realtek PXE ROM 2.48. If anyone is interested in trying this, let me know and I'll upload a version for all boards as a separate download. 

 
 
OK, so I have always been running my e770 system in AHCI mode b/c I like the ability ot hot swap drives - I even have a case that has 5 native hot swap bays.
 
Does this mean that if I want to switch over to RAID from AHCI I'll need to reinstall the OS from scratch?
 
Also, I have a pretty weird (but working, for me) setup, in that I have dual SSDs, one is DATA II and the other SATA II (but both connected to the SATA III interface) so I can split my Windows 7 install such that the Users tree and the ProgramData folders are actually located on the second SSD, for many different reasons.  Will this cause any sort of havoc for me if I decide to switch from AHCI to RAID after installing the modded BIOS?

Also, just a quick update in regards to replacing the Phoenix AHCI ROM with the one from Intel: There simply isn't any point in doing this, even though it is technically possible. My recommendation for everyone is to set your BIOS to "RAID" instead of "AHCI" and be done with it. That will bypass the AHCI ROM and just use the RAID ROM. 

 
 
So, we're still using the Phoenix AHCI ROM in AHCI mode?

i've updated the bios with the new irst rom and installed the new drivers, the crappy windows performance experince index for storage went from 7.8 to 7.9, performance increase confirmed 
i've also note a slightly fast booting / windows startup, consider the bloated task bar i have 
still ssd tool box won't run optimization on raid.. wonder if trim is going beneath it by windows it self.. 
thanks guys ! you rock ! 

 
 
New drivers?

henryvits 
For some reason, EVGA decided to include the JMicron RAID ROM with every X58 BIOS, whether the board has the controller or not. It is not being loaded if the board doesn't actually have it. 
As far as the Marvell RAID ROMs, they have to be flashed externally, and not as part of the BIOS. I'm sure you guys are already aware of this. 

 
 
Yeah, that is another question I'll post in the forums - I've found a few links to the most 'current' ROM and drivers, and I want to make sure I have the right ones....

Hey guys, 
I will upload modded BIOSes with the new RAID ROM as well as a new Realtek PXE ROM tomorrow morning when I'm at work. I've already modded my LE board, and it works fine. 
@dmoheban 
No need to release existing modules first. I simply replace the existing modules with "cbrom [BIOS name] /pci [module name]". The order of the modules shown with "cbrom /d" is irrelevant. The last one you update will always be at the bottom of the list, but what's important is that the letters A, B, and C still correspond to the correct modules. CBROM does that automatically. Also, the name of the module does not matter at all. It does not have to be the same as the previous one. 

 
 
Where do we get the module name from?
 
E.g. I downloaded the E77083.bin file - so I'm assuming that that is the [BIOS name] part, right?
 
Or should I just go ahead and make a bootable USB and copy this onto that and be done with it?
 
Or, as below, am I getting it wrong?
 
The "/pci nameofnewrom.xxx" command line is correct. The name of the replacement ROM does not have to match the existing one's. CBROM simply knows which one (A, B, or C) to replace. It won't ask you which one, like with "/pci release" or "/pci extract". 
 
 

Thanks for the info.  Time to get cracking on this.
 
Your help as well as the work you put into modding these BIOSs is much appreciated!

I think CBROM simply compares the size of the ROMs, which really never changes. I wouldn't worry about it too much.

@henry - I 'upgraded' to your BIOS mod, and everything seemed great - with a total of 6 SATA devices 2 SSDs on the Marvell (Micron-controller-based) III ports and 3 mech HDs and a Blu-Ray burner on the standard ICH10-based II ports, and all seemed well.  I even switched over to RAID mode from AHCI, and all went well as planned, no hiccups - or so I thought.
 
Last night I was trying to burn a disc image to DVD, and it kept failing - wasted a few platters trying.  Then I tried installing the original software that came with the burner (including the Cyberlink stuff so I can watch Blu-Rays) and that too failed - or, rather, more succinctly, it took an enormous amount of time, well into an hour and a half (nromally total time is about 5-11 minutes, depending upon the items I install).  Finally, I thought that I could simply make an image of the software install disc and load it into my Daemon Tools Pro software, but attempting to create an ISO from the software install disc *too* failed.
 
I thought it might be one of (new) my drivers, but device manager showed no issues.  However, it took forever to get into the Drive Manager console in MMC, and anything that used the burner or scanned it for contents would end up stalling as it just sat there unresponsive for tens of minutes at a time (Explorer, xPplorer^2, even at times IE and other programs).
 
I then wiped the SSds and reinstalled Win7 -
I removed all drives except the SSDs and burner and disconnected all hardware except KB and mouse when I did the reinstall - and disabled Windows Update so it would nto DL stuff in the background while I did all this testing - so it was a near virginal install of Win 7 (I say near b/c I use Audit mode to mode my user tree and ProgramData to the second SSD, thereby saving a ton of time when reinstalling the OS).  However, when I went to install the burner software again, *same exact thing* happened.
 
Next I thought about reverting to the standard .83 BIOS, but just before I was about to boot to the jump drive, I entered the BIOS itself, and scanned for changes - and then remembered that I had changed the SATA mode from ACHI to RAID.  Changed it back, booted back into (the newly installed) OS and tested, and sure enough, burner is acting normal again.
 
Thankfully this install was only about a month old.  However, thought you'd want to know that my burner refused to cooperate with the SATA seting to RAID even with no RAID volumes established.  Also hoping (!) that you might have some insight.

 Yeah, that really made me wonder why it was occurring.  I only wish I had thought of switching back before the entire Windows reinstall :P
 
It still seems odd, however, no matter how I look at it.  Oh well.  C'est la vie.
 

Hi thank you for the bios mods my E770 & E762 work great.
keep up the good work.

Hey Henry,
 
Have you tried that new modded Intel Raid Rom that allows trim to work on X58?

Not so anymore. I read that someone modded the firmware to allow operation of trim in raid upon ICH10R X58 chipsets. Only thing is some people had device conflicts with marvel controllers or worse systems that failed to boot on Asus X58 boards. Heres the link:
 
http://www.win-raid.com/t202f28-TRIM-in-RAID-now-available-for-ICH-R-systems.html
 

I'd try it also.

Great job! Any issues with your marvel controller?

Has anyone put together a modded bios for the E759 yet?

I'll keep watching this thread. Really looking forward to try out raid with trim enabled. Thanks, and good luck.

Well, I gave it a shot, and was able to modify my E759 and E760, both now have TRIM working. I did have to roll back the RST drivers to 11.7 versions and disable the Marvell controllers, but TRIM is actually working.

Update: Got Trim working as well. Trimcheck confirmed its working though you have to wait at least 20 seconds before trimcheck runs. Wonder if controller or drive is limiting factor in how long it takes system to trim sectors?
 
Thanks
 
Side Note: Now that this rig is obsolete I'm still getting some fun out of it in any case.

The 1.20E AHCI ROM is Intel. The one used in EVGA's X58 boards is made by Phoenix. We've tried to swap them in the past, but it never worked properly. Either way, they're both at least 3 years old, and neither Intel nor Phoenix ever released anything newer. The AHCI ROM is really only used at boot up and then hands everything over to the Intel RAID ROM. Not much to worry about.
