Guys hello! Sorry for english. I'm new in this topic and I do not know whether I'm asking this question in this topic - I have the GIGABYTE GA-EP45-DS3P motherboard. What changes can be made to this bios? I read you can change the AHCI ROM and RAID ROM - is that all? Here is the link to the BIOS http://download.gigabyte.ru/bios/motherb...45-ds3p_f9c.exe If it's not hard for you to see please. What can be improved in this BIOS. Of course I'll learn it.

@ Dagal
... additional you could update microcode (if there are newer ones), LAN Option ROM ...

@Dagal,

I recommend either making your own boot logo, or just clearing out the Logo files if you need space to add the Plop boot loader or just update the Raid Rom. Wouldn't go over 12.9 on Raid however.
Here is a good guide on adding Plop into your bios: http://www.rom.by/blog/Dobavlenie_v_star...pomoshchyu_Plop. Its in russian though.

Also thanks Fernando I didn't know about that PPMINIT issue. So Dagal read the thread Fernando linked and watch those checksums. Loading the final rom in Modbin6 might be could to check for errors,
and make further tweaks to the bios menu if you want.

Good luck!

Fernando, Yes I want to create a RAID array. Thanks for the answer. Now it became clear to me in general what to read and where to move. Thank you all, if there are questions I can ask them in this topic?

Fernando is OK. got it!

Which version of AHCI ROM is newer?
If everything is clear with the definition of the RAID ROM version, then there is no AHCI ROM.
1. I took from the bios ICHAAHCI_from_EP45DS3P.F9C (DEV_3A22) v.1.20E
2. I took from the bios ICHAAHCI_from_GA-X58A-OC (DEV_3A22) v.1.20E
3. I took from the forum ICHAAHCI_8086-3B22_v1.20E
According to the version they are all the same, but in HxD, they are all different. How to find out which one is the newest?

@Dagal,

I have zeroed out the old Sata RaidRom ver 8.0.0.1039 in your Rom bios and because there was enough room in there I added Raid Rom 12.9 but don't use it yet until someone like @Fernando can take a look to verify there are no checksum errors or anything in there. All I did was open your rom in a hex editor, searched for the -lh5- signature for the corresponding raid rom and two bytes after the filename entry and two bytes before the '-lh5-' signature of the next compressed file I filled it in with all '00's. This way it maintains the position of your PPMInit file. Only thing is I am not sure if it affects any existing checksums or anything however Cbrom was able to extract a perfect 64 byte empty zeroed out bin file. So thats encouraging.

I have attached the file as a doc file so rename the extension to .7z.

Thanks

@Fernando,

I don't believe that the name of the rom module is important. In my bios its called Sataorom.bin. What is important is the Vendor Device IDs and Rom Checksum information to be correct.
The problem with trying to replace the ICHARAID.BIN file with a dummy file using CBROM is that you can't predict the final compressed size inside his rom bios file? The way I did it the empty
module maintains the same file size compressed and uncompressed inside the ROM Bios file. The hope is that it would get ignored by the system when the system posts and uncompresses
the roms to memory. Of course I'm not sure if it would work because I really can't say if the -LH5- header maintains a checksum that needs to be corrected or not for each compressed volume.

If only Plutomaniac could comment..

Thanks

Fernando your probably right but there is no way to tell if his rom will accept 12.9 or not. If I was Dagal I would google search for already modified versions of his rom bios and see if others were able to load larger raid roms.
As far as the checksums are concerned I understand that part regarding how it works in respect to loading the rom. I would imagine that a file filled with zeros would get ignored due to not having a header, checksum, or anything.
If only he had dual bios switch or something if want to try it out without risk.

Thanks.

FYI: I recompiled a utility made by Pinczakko that corrects the checksums. It was so old that it would only work in a 32 bit dos shell but now works in 64 bit enviroments.

Here it is: Patch64

Thank you very much for your help and advice.
On the forum in the section Actual PCI ROM modules (not AHCI/RAID related) learned that in order to successfully insert the ROM into the BIOS file you need
a) replacing the DeviceID code and
b) Corrections for Checksum8
I understand that for AHCI and RAID, you also need to change DeviceID and Checksum8 (if DeviceID is different). All right and thanks to davidm71 for the Patch64

Thank you again for all your help.
