Actually, the list of "free" IRQs is determined by your system setup
and architecture. On a PC, the IRQs 0 (timer), 1 (keyboard), 6 (floppy),
8 (RTC), 13 (fpu) are reserved. The rest depends from your local setup.

Well, at least not if you're using the correct hardware to do that.

Sure.
You're obviously confused by the rather complicated setup steps that are
to be taken to have this working.
- It is a question of the bus/HW architecture , and
- it is a question of the drivers used.
A)
The classical ISA architecture _did_ allow IRQ sharing from the
very beginning (the AT&T specs describe that in detail). However, due
to the need to cut down the costs, the PC manufacturers took a different
approach. The "standard" PC board did not allow IRQ sharing in between
different ISA devices anymore, unless the HW used was specifically designed
to add that functionality that the boards did lack. A classical example
would be a serial multiport card (AST 4port, Cyclades etc., just to
name a few). These cards did provide the needed HW to have "level-triggered"
IRQ lines instead of the otherwise used "edge-triggered" ones.
Exeption: There are nowadays boards that provide the needed HW to
allow IRQ sharing even on the ISA bus, though possibly limited to the
serial ports only.
B)
PCI architecture was different from the very beginning. The PCI bus
did always allow for shared IRQs _amongst PCI devices_ . This works
very well, but not only does the HW have to support it, the drivers
for these devices does have to do that as well.
So the general answer would be:
PCI cards can share IRQs, ISA cards usually can't.
The problematic part , however, is finding out, which cards/driver
combinations do actually work with such a setup. This may cause some grief
during the testing phase, but it will for certain give you a valid
solution. Not all Linux drivers like IRQ sharing, especially if both
cards are using fast IRQs (e.g., a NIC and a SCSI card).
Presently, I do have
- all the standard IRQs in use (including 2 modems on the serial ports)
- a PS/2 mouse on IRQ 12
- a PCI SCSI card on IRQ _10_
- a PCI NIC on IRQ _10_
- a SB16 card on IRQ 7
- an ISDN card on IRQ 5
and I still do have IRQ 11 free (possibly to be filled with a
mutliport serial card really soon now...).

Hey bill thanks for yor help. I found someone who installed this modem on
Red Hat Linux 6.2 and many other linux versions. The problem is my modem
wasn't a win or linmodem (Thank God), but that it was a Plug and Play.
Thanks for help but I think these instructions will work :) I'll post a
reply to whether they work or not this week.

Hi,
Anyone got any info apart from HOW-TO docs on creating personalised root and
boot disks by hand (i,e, not using installation CDs to create them)?
Yup, another strange college assignment. Not looking for answers (obviously
;-), just a pointe rin the right direction of any help file stuff.
Tried the HOW-TO. The root disk I created gave me a "Kernal panic error" -
sounded pretty serious to me.

Christopher Browne's page is very informative, if not definitive:

I often look at this if I have questions about databases and Linux.
He also has some Linux pages below his general home page.

Not to me. Typical result of a foul up. Un-foulup. Possibly paying
attention to which is the root partition, depending on what the rest
of the error messages (unshown) were. You KNOW you booted the kernel
successfully, so the error you made must be later on. I vote for
"wrong boot partition", followed by "no support for root FS".

If you want to run windows applications, win4lin (www.trelos.com) is a
good bet, and it only costs 49.95.
The host of applications I needed to access without having to reboot
are: MSIE, Office 97, MoTMetaL Pro 6.0, ULead 5.0, Adobe Acrobat 4.05
(and Acrobat Reader) and NoteTab Pro. I use these in developing and
testing web sites.
Since I've installed it on April 6th, 2000, I have not had to reboot
into Windows to access these applications.
I do not need what it does not support: sound, vxd installed by third
parties or networking other than TCP/IP. It uses Linux itself for the
TCP/IP networking.
I'm not sure if it is an emulator or a virtual machine that can only run
certain OS's.

Star Office (free)
Applix (99.95)
WordPerfect (free, but limited fonts)
All will ''view'' the pages, which is good enough for many purposes. The
free version of WordPerfect doesn't support the fonts customers might
specify, Star Office comes mighty close, and I've not reinstalled Applix
since my last hard drive upgrade.
Unfortunately I need to see the pages as exactly rendered in Office
products, so I have to use Office.
Actually, I run Office 97 under Linux using a product called win4lin
(www.trelos.com). It allows you to install windows 9x onto machines and
run the applications without having to reboot. Well, at least in my
case, where I've not had to reboot into windows since I installed it on
April 6th.
I do web site development so I really need to see exact renderings of my
clients fevered ideas about their web sites.

Date: Tue, 02 May 2000 23:17:36 GMT
Hello, I have slackware 7.0 and will be installing it on a new computer
in a few days. Is there a single place on the net that has the updated
packages? For example I have Slackware 7.0 already, but, hdparm is out
of date so I will get the current hdparm. How do I know what is safe to
update and what is not?
I want to update my libs. We started off with slack 3 then 4 and now 7.
When we switch to 7.0 our cgi application has the time 5 ahead of the
system time. I did some research and it appears to be a bug in the slack
7.0 elf libs, or something like that??
I want all of the security updates, glibc, etc... I am totally confused
about this (as you can tell).
I downloaded gcc-2.95.2.tar.gz, but, I read that I should stcik with
2.72.3 to compile the kernel. Which one should I get?
I also downloaded glibc 2.1.2.tar.gz which is said to be the current
release on www.gnu.org, but then I found another site and download
glibc-2.1.3.tar.gz. Which one should I use and is it SAFE to install
them?
It is going to be a web server with http,ftp, and telnet.
Any ideas?

Both, obviously. Or neither. Do you want to compile?

You should use the one that slackware uses. No, it is not exactly
"safe" to install them, despite the patch level increment in the
numbering. (I speak having just won a battle with jdk 1.2 and
libc6 and X on my libc5 based systems - it was, uh, interesting).

Install slack and study bugtraq. Since you don't know about the
elemetary things, you shouldn't expect to be going round closing
unknown security holes for a while yet. There's a security howto.

Hm, a couple of possibilities. If there is such a script and you want
to find it, maybe something like:
egrep '/dev/(fd0|sda)' `echo /etc/rc?.d/*`
which will show every reference to the floppy or cdrom in the startup
scripts. You can sift through the results.
Another possibility would be to write a simple shell script that mounts
the floppy or cdrom, and make it suid root, owned and executable by the
group of people who you want to give access to.
Good luck,
Andrew.
