Back to the IDEBUS== Debate

**Rastar** · 03-14-2002, 03:14 PM

When I first started toying with Linux (mandrake 7.0) I noticed the IDEBUS== entry on init.

Well here is the updated version

Redhat 7.2
Kernel 2.4.9-31
GRUB boot manager installed
AMD Athalon 900
356 Megs Ram
Motherboard (Brand name forgot) that has a 233 FSB
IBM DTLA 40 Gig ATA 100 5400 RPM HD

Can anyone tell me how to better utilize the BUS and get rid of that error?

Thanks
Rastar

Where do you think you have to use this? which error were you getting? (sorry if I missed the previous thread)

I don't have to use any such statements, and I don't get those errors, yet I can run my hdd's at their speed, 66/100/etc....

hi Rastar,
I am really not sure what you mean, if you have an entry for GRUB (or had one for LILO) then odds are you don't need it anymore. here is what i have to get UDMA 66 working, my UDMA 100 controller is faulty...

/sbin/hdparm -c 1 -d 1 -X68 -S 180 /dev/hda

if you have UDMA100 trhen replace the -X68 with a -X69

Now does that go in my rc.d/init.d/??? file? so that the system will always use it?

And for all, the error shows up before the individual services load. The system still loads but it is an annoying little error I think I will try to post the error line from dmesg when I get home tonight.

Thanks

I put the /sbin/hdparm line in the file called harddisk or harddrive and rebooted. All is good now. Unless I should not put it there?

doh! *I guess i should put notification on...
on my rh system i have it in /etc/rc/local, *on my debain system i made a tiny script in /etc/init.d/hdparm and linked it in /etc/rc5.d/S99hdparm i think. that was the number... *

i don't know anything about the file harddisk - hey if it is working!! *
