Load modules at boot?

[miblo]

Hi,

How do I specify a certain module to load at boot time?

I have a RedHat 9 server and need the ide_cd module to load so I can use the CD-RW device. Manually typing 'modprobe ide_cd' loads it perfectly, but I want the module to load automatically when the machine boots.

Any pointers greatly appreciated.

TIA,

~Mike

The "Right Way(tm)" to do it is to alias the kernel resource that is being requested to the appropriate module in /etc/modules.conf

For example, these are from my laptop:

alias snd-card-0 snd-es1968
alias usb-controller uhci-hcd
alias wlan0 ndiswrapper

But you have to find out what the resource the kernel is requesting to do it that way.

Thanks, I figured as much. But how do I determine what the kernel resource is?

Specifically, I want to use cdrecord. cdrecord fails unless I do a 'modprobe ide_cd' prior to using it. Just running cdrecord does not automatically load the ide_cd driver, as one might expect.

So, how do I determine what resource cdrecord (or any other application) is requesting? This is my main issue...

I've never had to figure it out. Try this:

lsmod | sort > lsmod.out.pre
mod_proble your_module
lsmod | sort > lsmod.out.post
diff lsmod.out.*
