Hello everybody,

First of all I'd like to thank everybody that maintains and has contributed to this forum, finding informations was painless and was able to figure out most of the basic stuff.
I've just a few doubts left that I hope someone will help me clarify.

My current situation is the following:
- motherboard Asus P5K-E Wifi/AP -> https://www.asus.com/Motherboards/P5KEWIFIAP/ (P35 based)
- ICH9R
- already upgraded to latest bios version (1305)
- Intel MSM OROM version 7.5.0.1017
- 2x1TB RAID 1

I have bought a couple of 3TB disks to make a new 2x3 TB RAID 1 and replace the old 2x1TB but found out that my current OROM does not support the 3tb disks.

Now:
- I've understood that I have to mod the BIOS to replace the OROM with the 11.2.0.1527 and then flash it. Then I should be able to build a RAID 1 array out of the 2x3TB disks.
- I have also to use the 11.2.0.1006 RST drivers

Questions:
1) Has anyone tried this with this exact motherboard or similar? the closest I could find in the success stories is the one with the P5E, but didn't tested >2TB disks and a user that tried with the Asus Rampage Formula
2) I've read that in some cases the OROM was too big to include it in the BIOS. How can I find out if my board/bios/OROM setup is affected?
3) has anyone experienced data loss/corruption using the BIOS modding procedure?
4) assuming that all the above works, I've also the need about having the OS on the very same RAID volume, but I've read that there are limitations:
- OS needs GPT partition table to see volumes>2TB
- non UEFI BIOSes are unable to boot from GPT partitions.
What I don't understand is: if I create the RAID array with the RST BIOS tool, making a 3TB volume, then create i.e. three primary partitions of 1TB size (non GPT) and install the OS on the first one, will this be enough?

thanks in advance

Hi,

I have the P5Q3 Deluxe (P45/ICH10R) in my second PC. I was only able to update my OROM to 10.1.0.1008 because the BIOS does not accept modules above 85 KB of size. For your issue with your partitions I think you're right. Making 3 1 TB sized ones could be the solution. In my actual PC I have a 6 TB RAID-0 array and it was not seen under Windows Vista/XP until I installed ASRocks 3TB+ unlocker which came with my MoBo.
Think you have to try it out...

Regards hanson

Edit: Maybe you should create the partitions before installing with a parted magic linux boot cd.

just for my understanding, did you boot out of your array or you had another disk for OS?

thanks

@Fernando thanks for your feedback. The MMTools didn't gave me any error while updating the OROM, so I think I just have to try. I'll let you know the outcome (if I'll ever get my motherboard back alive :-D )

Hi,

I didn't get any error during replacing the modules. I could successfully insert all of them up to 12.x. But the computer does not post (hangs during RST notification screen) correctly and the RAID configuration tool is not useable in case I used any module above 10.1.0.1008. In this machine I use an array of 2 TB so I have no idea about the behavior with your 3 (6) TB RAID 1.

Regards hanson

Edit: It was not a problem of insufficent space I think but of the BIOS structure itself. I deleted the OEM logo, several unused Orom's to free space but thze result was same: nothing above 10.1.0.1008 worked. Anyway you should test it because for some ICH9/10R boards it's ok

Well, in the end i tried and it worked. I flashed the suggested orom with the latest firmware and now I have a nice 3 tb raid 1. A couple of notes:

- booting from a 3 tb volume is possible but you lose the last tb of space. This because the disk must be initialized as mbr instead of gpt, and with mbr there is no way Windows will allow you to create a partition after 2 tb. Don't know if gparted will, though.
- This is dumb but fooled me for a day: the Intel menu will not show up unless you connect at least two disks. At first I thought it wasn't working because I was testing only with one disk.

@Fernando do You want me to add this to the success stories?

That upgrade is probably just right for me, for using 2x3Tb in my RAID1 configuration on P5K-E (currently 2x1.5Tb).

But where do I find the Intel OROM update, and how do I use it?

Best regards,
