Ok, I just wanted to be sure you did things correctly, since I don't know how technical you are. Better safe then sorry...

In that case, if you didn't miss a 'hit any key to boot from CDROM', then you probably have a problem with your motherboard.
The drivers, from the motherboard company are windows drivers. They won't have any effect on whether or not you can boot to your CDROM Drive, because those drivers don't come into play until Windows is started. If your Windows Installation CD is a full-install disk, and it refuses to boot to the install, then the problem looks to be in the motherboard.
There is only one other thing that might be causing your problem, that I can think of, and that's a corrupt BIOS. I downloaded the latest BIOS to check it. It says it's for the following motherboards:
661GX7MI-RS
661FX7MI-RS
661FX7MI-S
661GX7MI-S
Since I couldn't find, the exact model number you posted, 661FX7MI, I would guess, that the Bios listed for the above models, should work on your motherboard, but I would call the company and verify this before trying to update the BIOS. Their number is: 714-871-9968. They can verify it's the correct BIOS, and then you can download it. They should also be able to point you to the correct download page for the BIOS download.
Here's the link for the page I found:

First Boot Device to 'Floppy'. Hopefully, you have a floppy drive installed. If not, maybe you can get one out of an old system you, or a friend might have, or purchase one from a used computer hardware shop locally, (They're pretty cheap these days). You might look into the BIOS and see if you can set the First Boot Device to a USB Drive, and boot from that if you have one pf those also. I couldn't see if that was an option from the manual, so you can check the BIOS or ask Foxconn to be sure.
If you can get a floppy drive installed, or already have one installed, then you'll need to create a bootable Floppy disk and place the two files in the BIOS download on that disk. If after creating a bootable floppy, there isn't enough room on the boot floppy disk, then you can place the files on another clean floppy disk, and once booted, remove the boot disk and put in the one with the BIOS files. Once in you run the AWFlash.exe to load the BIOS from the 'A:' prompt, (or whatever prompt the floppy drive shows after boot).
I couldn't find any exact instructions for running the AWFLASH.exe, so instead of my trying to give you the command, I would suggest you call Foxconn and have them give you the exact instructions to avoid any mistakes.
It's been a long time since I had to create a bootable floppy and I don't have any floppies installed on my systems to check things. If memory serves me correctly, you can right-click on the Floppy drive icon in 'My Computers' and the Left-click on Format. In the next window you'll see, you should have an option to create a startup disk. Then all you have to do is copy the two files over like I talked about above.
If you've never done this before, make certain you have the correct command line command for running the flash program and the correct BIOS file for your motherboard. Call Foxconn to verify all that.
Be Very careful, because if anything interrupts the BIOS update, anything, you could end up with a motherboard that has to be sent back to the company to have the BIOS flashed.
The problem, as I see it, is if you can't boot to a CDROM, a floppy drive, or a USB drive, then your only recourse is to send the motherboard back to the company to have them flash the BIOS. If you're not under warranty any more, you'll have to find out what they would charge for that service.
Keep me posted on what's going on, and I'll help where I can.
Good Luck!
