I have the following

ASUS P4C800-E Deluxe
Loaded O/S is Windows XP SP3
BIOS is 1023 in RAID mode with a single SSD

It has American Megatrends Inc v2.51 1985-2002 as the BIOS and the Intel Matrix Storage is version 8.9.0.1023. I know it is an old system that I just play with every now and then. So I'm bored and wondered if I can update that boards Intel MS. I read these instructions posted here and they are geared more for recent boards. But I see that there is one more update for Intel MS (8.9.1.1002) and since I really have nothing going on I want to tackle this.

Q1) How do I verify the last BIOS version had the 8.9.0.1023 (will use this method to determine if the new one took)
Q2) Using the MMTool for AMI, I pulled up the BIOS lines and found 3 entries for the PCI Option ROM (see attached). Which one is the one I need to remove/replace?
Q3) Is removing/replacing the Option ROM the same process written here as for newer boards?
Q4) Currently the system has Intel RST 5.5.0.1035, is there a better one for this older Option ROM? Does it exist?

Thanks everyone, I look forward to this project.

I must have something messed up here. When I am in RAID mode, during boot up a window quickly flashes. Over time I see Matrix Storage 8.9.0.1023 in upper right corner everytime I boot, but you are saying it is 3.5.0.3003 or something along that. Maybe I am catching some other number?

At the Asus site BIOS version 1016 shows a note; RAID ROM 3.54. I guess I am waaay too bored then. I will leave alone

I am running in RAID mode because I ran the SSD in IDE mode and it was really slow. I changed to RAID mode, load the Intel RST on to a diskette 1.44", loaded Windows XP from scratch, pressed the F6 or F8 thing and loaded the drivers. All went well and it is faster than previous IDE by a lot. Not as fast as today's boards by any means, but fast.

But I will leave this alone then, off to the other thread I started then.
