Subject: Question About IRQs and Chessbase

Author: Bob Durrett

I am thinking about purchasing a new computer and have a bunch of peripherals I
would like to use with the new computer in addition to my chess software.

My current computer has two USB2 ports and I have several peripheral devices.
In other words, the computer I have is not good enough.  Currently, my color
printer and my Chessbase software interfere with each other.  Chessbase ran fine
until I installed the color printer driver and started using the printer.

My impression is that CB8 uses an IRQ.  Does anybody know if that's right?  My
current computer, using Windows XP Home, shows only twelve IRQs in the device
manager.  Is that standard for Windows XP Home, or is that hardware driven?

If a computer has eight USB2 ports, it seems to me that that computer ought to
have more IRQs to handle all the extra peripherals.

I sure would appreciate any help with this.  Do I misunderstand this stuff?  I
am not a computer Guru.
