I have probably the worlds most expanded PC. The problem is that I have more devices than I have IRQ's.
Here is how my IRQ situation is at the moment:
00 - system timer
01 - Keyboard
02 - See 9
03 - Video capture card (PCI, Boca Video Phone BVPSZ1)
04 - COM1 (which I use for my digital camera)
05 - Realtek PCI network card
06 - Floppy Controller
07 - LPT1 (printer and scanner)
08 - RTC
09 - Creative Modem Blaster Flash56 PCI
10 - BusLogic PCI SCSI card (with int. CD-R and ext. Nomai 750 drive)
11 - USB controller (with Phoebe Micro USB modem attached)
12 - My MS/2 Mouse
13 - Numeric data processor
14 - Primary IDE (with 2 hard drives)
15 - Secondary IDE (with my CD-ROM drive)
So you can see that all my IRQ's are taken and my poor AWE-64 sound card can't find an IRQ.
I've already had to disable COM2 and the video card IRQ. I don't know what else to do except maybe disable the floppy drive controller and live without a floppy drive.
BTW the reason I have 2 modems is that one serves as my business fax and answering machine and the other is for my internet access. I could get another USB modem to give me another IRQ, but they are not cheap, and then I would have to add a USB hub if I got another USB device later.
If that wasn't bad enough, I also have a Palm Pilot cradle and a computerized scale I would like to attach to a serial port.....
Anyone got any ideas?
I was looking into one of those USB printer cables, but apparently you can only use them with printers and not other parallel devices, correct?
I'd wanted to get a USB mouse but couldn't find one with all the features I wanted (The mouse I have now has both horizontal and vertical scroll wheels and 2 extra programmable buttons (4 total).
I guess I am just going to have to change to a USB ethernet adaptor and USB video capture. Any recommendations? |

HI!
In some cases you can share IRQ among devices.
First, try setting LPT1 as EPP and not ECP
(in BIOS SETUP), this might free IRQ7 since
Windows can use it in "Polling" mode - without IRQ.
If no help, maybe setting the PCI modem on IRQ7 might
work. Also might work sharing modem and serial COM1.

Actually, I found a very nice device last night.
It is a 3 port USB Hub that also features a Serial port and a Parallel port.
If anyone is interested, they can find it below
