hi,

i know it's a pretty old topic but, may i ask you about your external battery pack, it's a 3x AAA ?

I have the same motherboard on my father's computer, the battery (already replaced long time ago) is dead and i wish to buy a battery holder but, the original battery was a 3.6v, i dont know if only 2x AAA -> 3V is ok or if it's best with 3x AAA -> 4.5V (close to 1V more than the original)

I dont want to fry this motherboard ^^

Thank you 😀

Ok I had a quick look, and yes, it uses 3x batteries 😀

😀 Thank you very much

By the way,

with 486 dx2 (at first was with a 486sx25 and 4mo ram)
(i didnt put pics of the original case since it's a post on the motherboard)

thanks to you soon he will have a new battery 😀

i have a similar 386 board running a am486dx40 chip but mine has a toshiba chipset + opti chip
the bios looks exactly the same aswell..
any ideas on what it could be? could it be the same exact board
someoen else said it might be a board called "robotech"
identifying a 386 motherboard? how to?

Did anyone tried soldering VLB slot to this board?

It's not a vlb slot! Mine has it soldered and I checked the vcc pins -> different from VESA pinout.
There is also a post from someone else here that tested it and it killed his vlb vga.
Better stay away from that slot 🤣

I see now. Now to find that "ECS local bus" Tseng 4000AX compatible card...

There was a pretty interesting thread on VOGONs a few years back about all the different proprietary local bus standards of the early 90s. This particular board happened to use one of those rather than the more common VESA local bus. The reason for not soldering the slot was that it would be easily confused with VLB since it unfortunately shared the same connector (with identical placement).

A similar problem happened with OPTi local bus, which shares the same connector and placement as EISA bus.

Pre-VESA Proprietary 32-bit Local Buses?

Hi have this same mobo, how do i install the math co? jumper settings needed? i currently have a 386 dx 40 on it and i want to install the math co but i don't understand in which direction the chip whould be installed in the socket

Thank you, i successfully installed mine but because i did not know which is the orientation yest i just find it with a multimeter and it works, i installed a cyrix 83d87 40 mhz fpu and now i can run some programs i really wanted to try on my 386, i will also try to install linux on it, i have to get some other hardware for that, including a floppy emulator and a second sd to ide adapter

I'm confused, what kind of external battery should I use for it?
3.6v Ni-MH rechargable or 3x1.5v AA non-rechargable?

Also any BIOS update for it?

Hi everyone, I wanted to let you know that I have a PC with FX3000.
The configuration is this:
MB EliteGroup FX-3000 UL-486 V1.0
BIOS AMI of 09-21-92
128KB Cache Memory
Cyrix CPU 486DLC40 40MHz
FPU IIT 4C87DLC-40
8MB RAM Simm 30 PIN 80ns
VGA Realtek 512KB ISA (expandable to 1MB)
HD Fujitsu 2613 135MB
In the past I remember having made some bench, I will try to do it again if you are interested.

I would appreciate it.
Not far ago i got a retro bug which evolved into quriosity about types and quality of old hardware, that i am trying to answer when i find the time for it.
Thanks.

These days I could restart it and see the scores it makes with the various bench.
I also have a couple of 80MHz DX-2 CPUs, I don't know if they can work, I tried another CPU years ago but it was broken.
One of the 2 CPUs is a Cyrix, I have never tested it, because it is not clear whether it is a 5V or a 3.3V.

So the FX-3000 is compatible with 5v DX2 CPUs then? Not sure if it'd make much difference with gaming in my case anyway since the bottleneck is the ISA video card I've got (some 512k cirrus logic card)

FX-3000 can work with DX2, DX4 Overdrive or Kingston AMD 5x86 Upgrade.

Certainly quite a nice range of CPUs it supports then, guess I'll be upgrading from a DX 33mhz to something a bit quicker

I found the bench results performed years ago with the FX3000 (486DLC40 IIT-487-40).
