assuming Idebus=33MHz

linux_pioneer · 07-20-2003, 02:36 PM

When I boot up redhat 9.0 I get this message about my hard drive speed. IDE assuming 33MHz bus idebuss=xx. I wish I could get the exact error message but my machine boots up too quick. Basically what its telling me is that redhat assumes my hard drive is moving at 33 MHz. Will this affect my system's performane? My hard drive has two speeds 66 and 100. Is there a way for me to change the speed that redhat assumes?

I wondered that same thing. Too bad nobody answered you.

Look in /var/log/messages or type dmesg | less in an x terminal to look for it.

My message is

ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx

I found this with a quick board search.

you're probably not using PIO mode anyways.
but if you do, just add idebus=66 to option past to kernel by your boot loader (with lilo, just add it to append=, I dunno with grub)

grub is similar to lilo. Insert idebus=66 at the tale end of the kernel= line after the LABEL=/ .
