Unhappy freeze during startup?


i'm trying to install linux on an old 486/33 with 16 megs of ram two hard drives totalling 1.7 gigs ( a 1.5 gig and a 200 meg ). the install process goes fine ( i'm setting it up as a router, and i managed to get the install down to 170 megs, not using expert mode ). the distro is Linux Mandrake 6.0. The only problem i have, is that after the install, when i start it up, everything goes fine untill it tries this:

"Starting Optimization of hdb [OK]"

and then it just stops. The strange thing is, at first, I thought the second ( 200 meg ) hard drive was faulty. So i removed it, and restarted. It complained about there being no hdb, and gave me:

"Type Ctrl-d to Continue or Root password for maintinance".

So figured it was hdb, shutdown the computer and reinstalled with just the 1.5 gig hard drive. Then it froze when 'optimizing' hda. So i know it isn't either of the hard drives. So does anyone have any idea how to bypass this problem? Or some way to fix it? (i also have the redhat 7.2 and redhat 9 cd's, but they both said that i didn't have enough memory )

any help much appreciated,
rebel

Hard drive optimization? I don't think I remember seeing that in my dmesg....

Personally, on an old system like that I think you might have better luck with slackware. I've installed slack on systems with as little as 8MB of RAM, so it should fly on 16. Their might be a kernel option that 'optimizes' the drives (not sure what this would do exactly), but I'm pretty sure the bare.i kernel does not include any optimization.

it's probably setting dma on or something like that and it isn't working
right. i can't remember where that old mandrake has those settings.
you might check the hdparm manpage for settings, and grep in the
/etc directory for some of those settings like
find /etc -type f -exec grep hdb {} \;

i think i remember an install option whether or not to optimize the hard
drives, and it's talking about hdparm. maybe it only shows in expert?

i just went through the expert install, and apparently for mandrke 6.0, there's no difference between a normal install and an expert install, except the default option goes from 'autoprobe' to 'specify' when adding cd-rom drives, network cards, etc. so what i'd like to know is how to tell the kernel not to do the whole optimization thing. the very last thing the install process asks for are things to be passed to the kernel before it boots up. so what would i put in for it not to do the whole optimiziation thing?

it's not the kernel doing that, it's the init scripts.
one nasty little trick you might could try would be, after the install finishes,
but before you reboot, to find hdparm, and rename it to something else.
that way when the init script calls it, it will just error. thats assuming it
uses hdparm, but i bet it does.

i guess you don't need to do it right after the install. you could boot the
cdrom, and mount the drive and go change it.
