P100 ISA Modem wont install.

Im tyring to set up an old p100. I have 2 ISA modems which I know work (they work in my p3450). The p100 is running win98. I put in either modem, and nothing happens. I jumpered them to com 3 or com 4, and run detect new hardware.

I dont remember ever having this problem back in the "old school days"

Any idea on how to get one of them to work?
 
Many ISA cards simply won't be detected. Assuming you have it jumpered for it's own com port and its own interrupt, it should work. You just need to add a modem in Control Panel and tell it what com port it is on.

Be sure it has its own interrupt - the default com3 IRQ is 4 which is the same as com1, com4 uses irq3 which is the same as com2. You need to have it on its own and make sure Windows doesn't assign something to the same IRQ - you probably will have to 'reserve' that IRQ in your BIOS.

 
Have you tried installing the drivers manuallyl? ISA peripherals aren't necessarily plug and play. Also you might want to jumper them to COM2 IRQ3 unless you have reason to believe that COM3 or 4 is what they will be happiest with. Also, you may have to go into the BIOS to bind IRQ3 to COM2 (or whatever) and force the modem to use COM2 (or your choice).


 
ISA hardware modems don't have drivers.

If you jumper the modem to com2/irq3, you have to DISABLE COM2/IRQ3 in your BIOS. The BIOS settings only assign addresses/irq's to your built-in ports. You have to disable that for another device to be assigned to those settings.
 
I want com2 irq 3. How do I jumper this bad boy.

Here is what it looks like (the #s are silkscreened, the . . are places to jumper, the _ are blank spaces). I have 4 jumpers.

Too many numbers, argh. 🙁
 
Most of the above help is correct...let's do it in steps.
1: go into BIOS and disable Com2.
2: jumper the modem for Com2, IRQ3.
3: install modem into the ISA slot.
4: in windows, manually add hardware, a COM2 port..
5: in windows, manually add hardware, modem, on the Com2 port.
when it asks for drivers, point it to them, or install generic
from windows.....
Good luck

I cannot figure it how to jumper to com2 irq3. I posted a picture of my jumper pins above. The label is all funky with 2 rows of numbers. 1 is from 2 to 12 skippin around, and one is from 1 to 14.
 


<< I thought it needed drivers. Where else would it get the modem string, etc >>


From the .inf file that came with the modem or was downloaded from the modem vendors website or by just using the generic Windows .inf file. It still is not a driver, just a text file.
 
bozo1, slightly askew of the topic, but you seem to be quite knowledgeable and I am very inquisitive.

Will you define &quot;driver&quot; for me.
 
I cannot get it on com2 irq 3. Every time I do that it freezes because com 2 is already on irq3. I cannot disable com2, nor can I move it. All I can move it to irq 4, which already has a diff com on it.

ISA sucks.
