Hi. I installed Fedora on a home Micron PC...
500MHz Pentium III, 640 MB Ram,
Promise Ultra 66 PCI IDE controller with 2 disks,
Plextor PX716A CD/DVD drive,
32MB Diamond Viper 770AGP (TNT2 Ultra) accelerator,
Creative SB Live soundcard,
Adaptec Ultra160 PCI SCSI for HP scanner).

I'm getting the following sequence of PCI-related messages at boot.
The "Failed to allocate..." message looks like an error. Also, does the
"apm: BIOS not found" indicate a problem? I've listed output from lspci
and lsmod below, in case that's helpful. Thanks for any help you can give.

Hi

This output does not appear to indicate anything that is a problem. The "failed to allocate" means that resource isn't being used, maybe because you have an empty PCI slot.

The apm message tells you that apm is not found in the BIOS, which is normal since you have ACPI, which is a newer version of power control, basically automatic shutdown.

Hope this helps

Bob

Indeed, do you actually have a problem? Something that doesn't work? Because if everything works, I have a saying for you that you'll probably already know:
"If it is not broken, don't fix it!".

Thanks for your help. I do have a couple of problems... no sound being one.
If the boot looks good, though, that's a big relief. How do you learn what
all of these messages mean? Can you point me towards a good reference or site
on the topic? I've got a software background, but I've never done much with
UNIX/Linux kernels or drivers. Thanks again.

hehe, Try this one , and in some cases The Linux Documentation Project is also a real help. Finding out what they mean isn't really important, if you have troubles with like say alsa in your case you run
To check out all the messages in which the word alsa is mentioned, if you really have an error concerning alsa, it will pop up.

Now to your alsa problem, I see your sound modules are loaded, so are you sure your mixer settings are not the problem? run alsamixer in a terminal and try and adjust the volumes.

Thanks for the tips. It turns out that I was not interpreting
Fedora's sound installation screen correctly. The volume was
extremely low. When I responded that I could not hear the
sound, Fedora uninstalled the relevant module. For various reasons
I went through the installation process again, this time increasing
the volume, and now have a fully working system. Thanks again.

No probs this is a common mistake, I think almost about everyone makes it . Ofcourse nowadays it happens less because the graphical installer try to handle these kinds of probs, but once in while it still happens.
When I started with linux 4 years ago, sound was hell to set up. Now that alsa is standard in the kernel much has improved.
