To see IRQ Details. Open Control Panel. Click System. Select Device Manager
tab. Then click Properties. IRQ details are shown there.

juggernaut, open this one back up...

1.how can you find out how many irqs you got left?
.Right click on 'My Computer' icon on desktop, select properties,
.Now click 'Device Manager' tab and select 'View devices by connection'
.Double click 'Computer' and you should have a list of irq's!

2.How many does a computer have?
.There are 16, numbered from 00 to 15, although some are 'reserved'

3.ok i want to install a voodoo2 3d accelerater card but im not sure if i have a spare irq,
   i have a ext modem, ps/2 mouse, a printer, sound card, graphic card, ide cd rom, ide    
   hard drive. would i have enough irqs
.Can't tell from that info.  Look at your list of irq's (from 1 above) you should be able to tell yourself.
   NB if you dont hve a 'good' sound card (like *real* SoundBlaster) it'll prolly be taking up 3 irq's (for WSS, Sound and Gameport)

4. Would a ext zip drive take one up as well??
.Depends, you can buy a parallel port one which doesn't use an irq.

wot only 15 points!  ;-)
Cheers MorFF

Yeah, if there's a gap, eg. no irq 12 in the list then it's spare.
A question mark means there's potentially a conflict with that device.  Go back to the 'Device Manager' tab and select 'View Devices by type', then double click on it and read what it says in the device status box below it.

(Remember to reject prev answer if you deem it no help.)
