I'm attempting to post stuff in some kind of chronological order.
My first build was the system above. I bought the board for £15 second hand in early 1998 when I was 15. When I first built it around the fullyes motherboard it had a Pentium 75 (O/c'd to 100MHz
) 32Mb SDRAM, Cirrus logic 5446 2mb pci vga card and an audio excel sound blaster compatible sound card, 2.1gig HDD and a 12x CD-ROM drive!
Because this rig kinda sucked I bought a new processor for it. I didn't know much about processors at the time, so I Bought a cyrix M2 PR233. Now I think with hindsight I could've got this chip to work on the fullyes board, but when I first tried it is said it was a 486. I didn't have the manual for the fullyes board at the time so I was unable to set the jumpers correctly (I set up the P75 purely by guesswork!)
So I went out and bought a new motherboard. This was it:
(pictured here with an S3 virge DX375 and a turtle beach aureal vortex sound card)
It's the widely acclaimed PC chips M571! So good, it has it's own website

What was 'great' about this motherboard was the amount of features it packed. Onboard sound, video, usb, IR. Fitted both AT and ATX cases, it was a real do-all board at the time. It supported high multipliers and FSB frequencies above 66MHz (but not 100MHz) So you had quite a lot of overclocking options. 75MHz FSB was a good setting, it oc/d the chipset though (PCI/ISA buses), so you had to be careful to not push it too far.
What the website doesn't tell you is if you don't want to use the on-board sound you can't use an add-in sound card in dos. It causes some kind of hardware conflict even when you disable it in the bios and with the jumper on the motherboard. Which wasn't good for me as I still played a fair few dos games, like first encounters and I wanted to use a decent sound card. I think I had a PCI64 at the time (Still got it!)
The biggest problem with this board though is it's memory performance. The fullyes board even when using EDO ram could run rings around this, even when you ran the M571 at 75MHz with SD-RAM.
Real world performance isn't too bad. If you run it at 75MHz you get a nice boost in graphics card performance. I did some comparisons with 3dmark 99 a few years ago and it was better than the fullyes board by quite a bit, I could also run the CPU at the full 450MHz and it supports more ram
So really, in most respects this is a better board than my old one, but being unable to use a proper sound card was a deal breaker for me. So now it sits in its box in the attic as my backup should I ever need it. I hope that I never will!
I only discovered all this more recently. I used this board for about a year before I moved on to an Aladdin V chipset MSI board which supported 100MHz FSB and AGP (to some extent, but not very well).
