My m/c is a HP Compaq dc7100 CMT(DX438AV).
I've replaced the 2.8 processor with a P4 HT 3.4ghz 1M/800 SL7PY , during start-up it gives the message "missing or invalid processor microcode update"
My motherboard is HP 0968h . My Bios is... Version : 786C1 v01.05
I looked at specs for the board and i think it supports this chip, can anyone help fix this problem

The new CPU has a different stepping than the old one. You will have to update the ROM chip (no BIOS) or something like that. Call HP support and ask them..
You can also try to install this: http://h10025.www1.hp.com/ewfrf/wc/softwareDownloa

Now that you installed the latest microcode update, may I recommend you install the Pentium 4 650 3.4 GHz?
That processor has double the L2 cache as the one you installed, and you can run a 64 bit operating system on it.
If you have the CMT, you have a pretty wide assortment of video cards you can install so you can run all of the features of Windows 7. The onboard GMA 900 video won't run Aero. Just keep within the power supply limit of 345W
I have W7 x64 on my dc7100 CMT and an ASUS nVidia 8400GS 512 MB fanless video card in mine, and everything works great. Recommended P/S is 300W for the card so I was fine.
The P4 650 is pretty reasonable on eBay. That is where I got mine.

The only way you can run the microcode update is with a floppy drive.
When you double-click the executable, it creates a bootable floppy and you just boot from it and follow the on screen instructions.
The problem is...since you installed windows 7, I do not believe that utility will run on W7.
You need to run it on XP to create the floppy disk. Once you create the bootable floppy you will be fine, since you will be running the microcode update by booting from the floppy disk.

You're very welcome.
I have given you the only solution to the problem that there is.
1. You must use a floppy disk drive and a floppy disk to run the microcode update -- a USB floppy drive will work.
2. In order to create the bootable floppy, you will need to find a computer running windows XP or windows 2000 in order for the executable to run and create the bootable floppy.
I tried runnning it using windows 7, and it doesn't work.
There is no other way...
