IRQs, PCIs, linmodems, life ...

No-one on this forum seems to be really up to speed on IRQs.

There's a really thick book in my local library computer section called 'IRQs' (if you've read it, please share your insights!!) and I regard it in the same way as 'War and Peace' or 'North and South' or other large 'X and Y' works of fiction.


I had IRQ conflict problems - the sound and Winmodem both wanted IRQ11. So I set all of the IRQs to 'autoselect' in the BIOS, compiled the module and inserted it at boot time using the /etc/rc.local file. I didn't insert it directly because the init didn't like it, so I made a file called 'linmodem' :

insmod -f /home/kernelbits/ltmodem.o

and made it executable

# chmod u+x+g linmodem

put it in the /usr/bin and entered it in the rc.local file:


It's perhaps not the most elegant solution but hey, I like Perl programming so what did you expect?

OK, then. No problem ...

For RH7 you probably need version 5.78f of the linmodem driver. I am assuming you have the Redhat 7.0 with linux kernel 2.2-22.16. Check with:

[root@bigtree root]# uname -r

Get the file with the extension .tar.gz

The .gz is a zip algorithm to compress the file to unzip it,

[root@bigtree root]# gunzip ltmodem5.78f.tar.gz

(the file will now change into ltmodem5.78f.tar)

[root@bigtree root]# tar -xvf ltmodem5.78f.tar

(the .tar is a way of 'globbing' files together to make one big file. The command above unglobs them into separate files)

[root@bigtree root]# cd ltmodem5.78f/

After you've unzipped it, you can browse the contents of the folder using the graphical browser. You'll come across a file called README. Left click and choose 'view'. This file will have further instructions on how to compile the module, which will appear after you've made it as ltmodem.o

The README files can look a bit cryptic at first, but just read what it says and do what it says, and you'll be fine.

Let me know how you get on.
