Kenn, 

I checked Windoze and the IRQ is 7, port 0x378 (this
appears to be normal). 

The devices files are as follows: 

crw-rw----   1 root     daemon     6,   0 May  5  1998
/dev/lp0
crw-rw----   1 root     daemon     6,   1 May  5  1998
/dev/lp1
crw-rw----   1 root     daemon     6,   2 May  5  1998
/dev/lp2

Here is the output from dmesg (notice the last line -
I am only after noticing it myself)

It does appear that Linux cannot see the port due to a
BIOS setting. I have tried every combination in the
BIOS - so now I am going to trash Red Hat 6.1, install
5.2, make sure it sees my paralell port and upgrade
(as opposed to install) to 6.1. This should do it. 

Let the fun begin...

Trevor.
