"loading slackware" take a long time


i have slackware 13 installed on 3 different computers. on two of them, the "loading slackware" step at the beginning of the boot process takes maybe 2 or 3 seconds. on the 3rd it takes a good 30 - 60 seconds.

any clue as to what could cause this, or where i should start digging?

thanks!

Are you talking about when the kernel is being loaded by lilo and you are seeing the line of dots? Are you using the huge kernel on that machine? Is it significantly older or less powerful? Slower RAM?

You can also check out my sig where I "made an attempt" to reduce boot time.

yes, that's the step.. "loading slackware" and the line of dots. i am using the huge kernel, but this machine is by far the most powerful of the 3.

If you use compact in /etc/lilo.conf, it speeds it up considerably.

it just occurred to me that this might have something to do with the fact that this machine is 64 bit, and the other two are 32. when i installed, i only saw the one dvd image, so i assumed it was all on the one disk. but now that i'm looking at some other mirrors, i see some 64 bit images available.

everything else works perfectly. it's only loading the kernel that is off. could this be caused by using 32 bit on a 64 bit system? i would think that i wouldn't have been able to install it at all if it wouldn't work....

Try booting generic on the same machine, you won't lose any functionality, but you will need an initrd. I use custom kernels and leave out as much as possible that I KNOW for certain I'll never need. It speeds up considerably over generic even. Although 30 to 60 seconds seems EXCESSIVE for anything.

What is the specific proccessor?

i might have time to create an initrd and boot generic over the weekend. this is a work computer and i can't do too much tinkering while i'm at work.

about the processor, the machine is a travelmate 4720, and according to a cursory search it appears to have an Intel Core 2 Duo T7300 / 2 GHz ( Dual-Core )

It just occured to me that you might be booting from the USB stick created during install? If that is in fact the case, then I do not have any idea for you other than to install a local bootloader. The USB stick is a painful experience for daily use, though a lifesaver for "OH S#!7" moments.

That processor can be used for 32 or 64 bits. I have a similar laptop and it runs 32 and 64 equally well although I've never run slack on that machine.

Not to assume you don't know, but if you aren't familiar with any of these things:
With BOB's script you can create your initrd in seconds, and lilo.conf can be edited in under 3 minutes, lilo can be run in another 25 seconds and then you just have to try and reboot.

i've never actually tried booting from a usb stick. i installed on all 3 machines from a dvd image, and now boot from the hard disk.

thanks. i've built a custom kernel and initrd before, but not in a long time. i'll give it a go sometime soon, hopefully by the weekend.

Try using
Code:
# Start LILO global section 
# Append any additional kernel parameters:
append=" vt.default_utf8=0"               
boot = /dev/sda                           
compact

my laptop first loads:

loading linux ..........................................
................................................

then it begins mounting filesystems and checking other hardware

and it takes 30 to 60 seconds, i thought that was normal , but now that you mention that slackware in the other PCs take about 2 to 3 seconds, thats a pretty impressive amount of time

well.. not really. there is no reason it should take a full minute to load the kernel. the two computers i have that take 2-3 seconds for this step are both approaching "elderly" and they handle it just fine.

do you mean the whole boot process takes 30 - 60 seconds? or just the "loading" step at the beginning?

once my kernel is loaded the rest of the process flies by. it's only that first step that drags.

Have you tried what manwichmakesameal said?

compact
To explain a bit more, he means:
-Edit /etc/lilo.conf
-Uncomment 'compact'
-Run '/sbin/lilo'

If that doesn't work, I'd try using Grub
