Before we start I'd like to thank feipoa for helping me out. He knows this board inside out 😀

The reason for this thread is to compile all the interesting aspects of this board in a single place!

Picture of the board with ODIN RTC removed:

When I received the board it came with a ODIN RTC with a dead battery. For some reason this board does NOT store BIOS settings, even when powered on. The board would hang at this screen:

Removing the cache chips solved the problem

but replacing the ODIN RTC with a DALLAS from eBay fixed the issue of the board not remembering BIOS settings. I wanted to put a socket it, but couldn't wait and just soldered in a DALLAS from eBay 😀 I had to de-solder a jumper which was blocking the DALLAS from fitting. I believe it's the clear CMOS jumper.

I proceeded to set the time and load the BIOS defaults and the board hung again at the same point as before:

In turns out I had to set the option "EDO DRAM installe option" to "Enabled". I didn't change any other settings, I never do as I value stability more than speed tuning 😀

Currently the board is fitted with 256KB 15ns Cache, an IntelDX4, 16MB EDO memory (LGS branding on 8 chips) with 60ns. Video card is a PCI S3 Trio64V+ with 2MB and for storage there is a floppy emulator and a 2GB CF card with a single 500MB FAT16 partition.

Here some images to check out!

nice pics!

Good to see you putting down your Socket 7 rig to use this motherboard Mau1wurf1977:)

It's a quality board for the 486/586 platform - fast, reliable and compatible 😀

Oh I got 4 new SS7 boards, don't you worry 😀 It's still the ultimate time-machine 😁

But finally having some 386 and 486 gear is also very nice. Allows me to make some comparisons and I have a few videos planned as well 😀

That is one serious sweet setup! Should be lightning quick too with the CF adapter. 😁 The S3 Trio64V+ was a pretty good card back in the day too.

How/where did you get a floppy emulator? How does that work?

One thing I'd do is ditch the Logitech mouse driver. I remember that one as being a memory hog. Unless you're loading it high, then it's all good. 😉

I love the Logitech driver. Used it as a kid and I need that blue box when it boots 😁

Memory isn't an issue. I have built a multi-menu boot menu and the system runs everything from Wing Commander to Ultima.

I use that driver too, love the blue box but it also has a 'cloak' function which hides it in upper memory somehow, then it only takes up 1K.

Life? Don't talk to me about life.

List them please!!

Two DFI SS7 boards, a Gigabyte board with Intel chipset and an Asus board with SIS chipset. All ATX!

I haven't tested them yet, but they all look fine.

I know what you mean! When we first got that driver, I loved it. Then when I was optimizing our memory configs, I had to ditch it, 🤣.

Neat!

My inventory of ATX SS7 boards:

DFI K6XV3+/66
IWill XA100 Plus
Gigabyte GA-5AX rev3 -- needs re-capping
Freetech/Flexus P5F103
AOpen AX59Pro -- On my way

All of these sport 3 ISA slots. (except AOpen)

I'm still in the hunt for a few others.

RTCs can burn in hell. The bane of my existence.

But Mau1wurf1977, I simply must know where you got that chip programmer? That's an incredibly useful piece of equipment!

So many combinations to make, so few cases to put them in.

Probably eBay, from some chinese or Hong Kong seller.

Yes I got it from eBay Asia 😀

It crashes on my desktop, I think the CPU is too fast. But on my notebook it works fine. Used it with some other chips as well. From AMD and Windbond in SS7 and Slot boards. Works very well and easier than doing it in the PC...

Plus, it's a valuable piece of equipment even to preserve old hardware. Imagine somthing goes wrong with precious vintage video card BIOS. Good luck finding a BIOS file for that card on the internet. Good thing that you backed up all your vintage cards BIOSes...

Yea it's a very handy device!

Found another BIOS online! From this site:

http://ftp.mpoli.fi/hardware/ROM/OTHER/

I attached it to this message.

BIOSTAR MB-8433UUD v2012 is the same as UUD960520S, but with some features unhidden, most importantly, the ability to change the TAG SRAM bit, allowing for L2 write-thru cache.

To have a tuned BIOS (optimised), you want to enable "slow refresh".

Did you notice any benefit when setting the "EDO DRAM Read Speed" to 3-1-1-1? I unhid this option to test it out. It is 4-1-1-1 by default.

What are those desolder tips you are using? Is the pump part of the solder tip? How would you rate its ability to desolder compared to a separate iron and hand solder sucker?

Plan your life wisely, you'll be dead before you know it.
