Add in Controller card info

I have an add-in Controller (ISA) that I am needing more info on. I need something to tell me what jumpers should be where for a particular setup.
There isn't a name on the board anywhere so the best info I can give is a discription of the board and the FCC ID #.
this card has a parallel port hard connected to it, it also has a 9 pin serial port attached by flat wire, alos a 25 pin serial port attached by flat wire, also a 15 pin female connector attached by flat wire (says game by the board connection), Now there is also a connector for HD and Floppy too.
This isn't for a new computer or anything but I'm thinking it may come in handy when working on an older computer someday, but in order to be able to use it then I need to know the jumpers setting on it.

Forgot this, there is two chips on it that is about .5 X .75 in size with the name "Holtek" on them if that is any clue.
Here's the manufacturer's web page, but I didn't see anything about your card. Holtek seems to make a lot of things, and I doubt they will support such an old card
Just for future reference, you can find the manufacturer from the FCC ID at
Well you have your average generic multi I/O card there, the FCC number gives Holtek as the Manufacturer, but they are just the semiconductor people really, probably they got the design approved and let half a dozen small sweatshops bang them out and support them.

What and where are the jumpers? I might be able to match them with other cards, a general layout pic or diagram of the card would be very helpful.

I looked all over the Holtek site, nothing helpful, unless you want to know how to make an i/o card with the chips that are on it.

It is possible that you will find a match in these DTC designs....

about half of them are winbond chipsets though.

if there is a near match in layout in any of those, say which one.

still looking,

Woohoo, fortune doth smile on you, first I/O card out of my spares box is a LCMSIO-2A with the JUMPER SETTINGS PRINTED ON IT !!!!!!

The block of 8x3 in the angle of the Floppy and IDE connectors...
Stars next to defaults (single i/o card in computer, no onboard i/o)
1 is up.
1st is GAME PORT 1-2 ENABLE 2-3 DISABLE-- Disable if you have one enabled on soundcard otherwise enable
2nd is IDE PORT 1-2 * ENABLE 2-3 DISABLE

4th, 5th, 6th, 7th, 8th = J1...5
 J2  J1   PRINTER PORT (Parallel Port)
2-3 2-3   DISABLE
2-3 1-2   LPT1 * (378)
1-2 2-3   LPT2 (278)
1-2 1-2   LPT3 (3BC??)

  J5  J4  J3  UART1   UART2   (com connectors 1&2)
2-3 2-3 2-3   DIS        DIS
2-3 2-3 1-2  COM1    DIS
2-3 1-2 2-3   DIS       COM2
2-3 1-2 1-2  COM1   COM2 *   (3F8, 2F8)
1-2 2-3 2-3  COM3   COM4     (3E8, 2E8)

The second block of jumpers, underneath the 15pin game connector are the UART IRQ selection Jumpers.
1-2 UART 1  (com connector 1)
2-3 UART 2  (com connector 2)

and reading left to right the settings are IRQ3 IRQ4 IRQ5 and IRQ9
In a standard system IRQ3 should be jumpered 2-3 for UART 2 and IRQ4 should be jumpered 1-2 for UART 1, the others should be OFF (not connected)

The 2 pin jumper between the game port and the IDE connector is the HDD LED connector, pin 1 (+ve) is to the left. Pin one is at the top for the floppy connector and to the left for everything else. (That's where the red stripe goes)

No drivers are needed or available for this card, it doesn't do any fancy I/O modes or have enhanced disk drivers, UARTS are 16450 compatible.

If you need any clarification on that, just ask :-)

Oh, I'd print and save that if I were you, I have seen the odd question lose it's text when the site is updated, so if it is a few months before you use the info it has a 1 in 100 chance of not being here still :-\

Thank You

Could this card be used alone as a second parallel port to hook up a printer, scanner, ect??  Would there be a problem with that???
Yes it is perfectly possible to put it in as a second parallel port, to do that, you would probably find most success if you disabled everything but the parallel port, which you would set to the LPT2 setting. You could get an extra comport out of it, but if you already have onboard comports and a modem it is most likely to argue with them somewhat, so best to disable them. The parallel port should be new enough to be bi-directional and is probably an enhanced parallel port, most new scanners and printers should work with it.

So that would be all the jumpers down, (2-3) in the first block apart from the fourth one, which should be up (1-2)
