I want this thing go faster!
My p200MMX (socket7, and bus can go upto.. about..70-80 I think..) machine got (single boot) Red Hat 7.1 installed on it and I can't help feeling that it's bit sluggish..
(it's got 256mb pc133 sdram.. 🙂)
Redhat is installed as workstation level. I just couldn't be bothered to manually partition the HDD and selects the packages..
Is there a way that I can make this thing go faster?
and.. how do I know whether my hdd is running with DMA mode enabled? (udma33 hdd)

HDD: at a command prompt (I know no other way) type: dmesg | grep hda And see what the output is.

As far as making it smoke, uninstall X, recompile your kernel with as few extras as possible and tweak it for your cpu, recompile userland for your cpu, cut down on running services, and you should be set.

At a console as root, run &quot;hdparm -v <hard drive device>&quot;. That should give you the info you need. Read the man page for hdparm to find which parameters enable which options. Your hard drive might be using DMA by default; I've rarely seen it happen where it doesn't get set that way by the kernel. However, you may need to enable 32-bit disk access.

It is more likely to happen when you have old hardware and a new kernel. RedHat 7.1 on an old PPro machine should enable everything just fine (unless he has some funy disk controller in there but if he did it would be ATA66/100).
