 Post subject: Speeding up Boot time
PostPosted: Sun Jul 04, 2004 10:57 pm 
I am wondering if anyone has any tips to speed up the boot process.

Mine seems to take the longest when it looks for drives. Since I have a master on ide primary and a slave (DVD-ROM) drive on the secondard ide it waits while it scans the ports on every boot.

So are there any tips to stop this, and in general speed up linux booting?

well usually that port scan is from the bios. you need to go into the bios and choose none for the places you don't have any disks. as for speeding up the knoppmyth boot there is not really much you can do it is rather stripped down and parallelized as it stands.

nah that scan is 1/2 way through the boot. My bios is set so only the two drives that are there are shown the other ports are set to none.

What would you describe as "the longest time" is that like 20 seconds, or 5 minutes?

Numbers would be great.

What type of PC / CPU?

well i would put it down to aorun 8-10 seconds per port that doesn't have adrive connected. CPU is a AMD Duron 1200.

My thought is there must be a way to get it to save what it has found so next time it doesn't have to do the check again.

that's very odd cause I have a harddrive on primary master and a cdrom on secondary master, and nothing on the slaves and the drive detection on mine might on the high end take 1 sec. goes so fast you can only see it if you look for it. Are you using scsi disks or sata or ide raid or something else odd/different? if not what chipset is your motherboard using?

This is fairly normal for some ide chipset types. Namely cheaper VIA releases.

The solution is simple, simply load up the bios settings and disable the "AUTO" section for the channels with no devices.
You'll likely see if on the far right of the hard drive listing, turn it to OFF
... asuming it's an award bios.

when in doubt consult your motherboard manual.

I see the same thing. I doubt it is the bios since it happens 1/2 way through the linux boot.

I do have my CD connected to the secondary slave, with nothing in the secondary master. I think this may be causing it (linux looking for the master). Maybe you have done something similar?

I've been meaning to fix this, but haven't gotten around to it yet... I want to have enough time to fix up the mounts that I expect will break when it moves from hdd to hdc.
