PCChips (maybe a P54C) => ongoing

[mahib]

Dear friends,

I think this a bit akward but I do need help, a lot.

I have and old motherboard from PCChips that I do not find in the web http://www.pcchips.com.tw. Stupid of me I lost the manual so I am completely losed.


It has a Socket 5, an AMI BIOS, 4 ISA slots, 4 PCI, 2 IDE controllers on board, 4 banks for memory of 72 contacts and the only IO system is the keyboard connector (the big one -not PS2). It is equiped by a Pentium 90.

I can not help more because I do not have a power supply with the same interface that is currently avalaible, so even I can not even start the motherboard right now. Maybe I can find a conversor but I prefer identify the mobo before I plug it anything.

I searched a lot of webs on the Internet watching pictures and the only that can be very similar are the mobos based in the old Triton chipset of 95.

By the way, navigating in http://www.x86.org/intel.doc/intelmotherboards.htm the most similar motherboard is the Zappa Advanced/ZP Pentium P54C, Socket 5, 82430 FX Triton Chipset.

A friendly guy posted the photo of the mobo in http://s87841630.onlinehome.us/MBHW/placa_base.jpg.

Can anybody recognize it?

Thanks in advance,

Mahib.

Hello (again):

I got an AT box with supply so I plugged the mobo but it does not work.

I tell you what is plugged if can be helpful:

* A floppy unit connected to an I/O controller I bought in a second-hand store. The problem

is that the brand is NEIMKI (stands for "Netiher it's Mother knows it") and has a lot of

jumpers without any legend. I searched for the unique indication (JGBPRIME2) on Internet and

the result was zero.
* A Toshiba CD-ROM on the IDE 2.
* A Cirrus Logic graphic card in the VGA SLOT.
* A Realtek 10/100 LAN card.
* A Pentium 90 en the Socket 5.

So I start up the computer and nothing happens, there's no bips nor the monitor shows

nothing.

If the mobo is not completely dead, maybe the only thing I did wrong is plug something in th

wrong order.

I'll check it to see if somebody can help. Please refer to the URL http://s87841630.

JP2: there's no legend. It is under the external battery and below the keyboard

connector. It has jumpers in the 2-3 positions so I left it (the first position is

hidden by the jumper.)

JP6: It's on position B. If you pay attention to the right-central part of the

photo you'll see the legend 75M, 90M, 100M. Hidden by the memory chips on-board it's

the JP6 legend. It's destined to the chip speed. B is the position for 90MHz so

the position is correct.

JP7: No legend. I left it as is.

JP10: it's near the 91A/DY chip. No legend, no jumper. It was originally as

this? Did I take off the jumpers when I "parked" the mobo? No idea.

JP11: it is the TB LED. I guess is the "TURBO" led the mid 90s mobos had. I

plugged the connector of the box.

JP12: it is the POW LED/KEY LOCK. I plugged the box connector and works. At

least the POW LED because the KEY LOCK I had no opportunity to check.

JP13: it is the SPEAKER. In the box there was no connector with the this text

but following the only connector that has no legend I reached the speaker so I plugged it.

JP14: it is the TB SW (¿Turbo Switch?). There was no connector nor a switch on

the box so I left it as is.

JP15: it is the HDD LED so I plugged the box connector with this legend.

JP16: it is the RESET so I plugged the box connector with this legend.

JP17: it is the SUSPEND SW (?). It must be the suspend switch. There was no

switch of this type in the box so I left it as is.

The FAN POW connector below the micro socket I left it empty because the fan has a

male big connector to plug one female connector of the power supply. And works also.

The supposed 1, 3, 4 and 5 jumpers does not exist so there is no comments.

Some of the jumpers I talked about are not visible in the picture so I indicate them.

From the right down border of the picture and from top to bottom and right to left are:

13
12
17
16
15
14
11
7

I do not know if to give up. If somebody has and idea...

Thanks.

Sorry for the delay in replying.

Have you tried the PC-Chips Lottery? You will need to know what chipset is on the board.

The link to the picture does not work.

A ggogle search for JGB<space>Prime2 brings up a reference to this being the FCC ID. The FCC ID JGBPRIME2 was allocated to the Gold Star Electron Co. Prime2 Multi I/O controller. Check out http://www.anime.net/~gigagon/isa.htm and see if one of the Prime 2 cards there matches yours.
This is a good site for I/O card info as well, run by our Edwin.

I've been given the board a few days ago by Mahib... The world is tiny... he's an old friend of my sister, and works a few hundreds of meters from my house
...Sorry NickS, yards for you

In a few days I'll try to get deep into the board... haven't unwrapped it yet.

Hey, I know what a meter is - it's American for what the French call a metre.
