New hard drive controller

[Lnlpawpaw]

I am running an IBM Aptiva 2152E2N and would like to add a new hard drive controller board. The one that came with the machine is on the motherboard and is ultra 33. I want to add a pci card that is ata 100. How do I disable the onboard controller?

Thanks,
Pete

Why do you need to?

 

[Enkrypted]

You should be able to put the card in the system, hook your drive to it, load up the drivers, and make sure in the BIOS that it is set to boot to that device first. Enkrypted

Bought a 24x10x40 cd/rw for backup. Had nothing but problems. Seems my hard drive only runs at 18 mb per sec which relates to about 15x. I replaced the hard drive some time ago with an ata 100 drive. Now burning a lot of coasters as drive output so slow. Want to see if new controller card will help. Cards are cheap ($25.00) and I have an open slow. Just don't know how to disable onboard controller.
Thanks,
Pete

Don't see how disabling onboard controller is going to affect your new controller (they're separate devices - the new one is just additional - if you attach drive to it, doesn't matter if on board controller is disabled or not) - but you should be able to do this in the bios (just get into bios settings and have a look on the various pages).

Unless I am mistaken. He bought A Promise card ATA 100. I do not think that it will allow you to boot from that device. It still has to use the primary IDE as the boot IDE. Unless they have changed in a couple of years. I had one. It worked great. But I could not boot from it. Also I had to have at least one H/D hooked to it. I could be wrong.

Everyone has their two cents worth. Lets all try to donate our two cents and maybe we all can come up with a Dollars worth of advice!!!!!

Just a thought . .
My specialty is digital media, and a flag went up when I saw your numbers.
For all CD based media . .
1x = 125kB/s
therfore
15x = 1875kB/s = 1.875MB/s
If your HDD runs at 18MB/s then it's running at about 144x.
Odds are your burner problems aren't bus related. The speed ratings you've given mean that it's a new enough burner to perhaps have buffer underrun technology. If so then it should be near impossible to make a coaster unless you're working with odd DAO required images and other weirdness (not just music or computer files).
All sorts of stuff can affect burner performance . . .
HDD fragmentation
Driver problems
ASPI layer issues (for some software)
CPU load and low free system RAM

Try defragging first. If you know that's not a problem then check Device Manager to see if you've got duplicate drivers running or any strangeness like that. You may also want to check and see if you have the newest chipset drivers for your motherboard, as that sometimes weighs in on IDE performance. You might try quitting other memory resident programs and refraining from doing anything with your computer while burning. In essence, streamline your system for burning to see where the problems lie.
You may also want to check the specs on the burner to see if it's capable of speeds faster than UDMA-33. Though I'm sure it's becoming more common, last I knew most were no faster than that anyhow.
About disabling the onboard IDE controllers, there should be a setting in your CMOS/BIOS menus to disable onboard IDE by channel (primary/secondary). Some old rare MBs had jumpers onboard to disable nearly everything, including IDE, but I'm 99.9% sure you don't have this option.

I hope I haven't flooded you with stuff you've already tried or already know. I've a bit of passion about this as I have keyboard shaped impressons on my forehead to this day from the trouble my old burner gave me. I can almost guarantee you that your problem is software or driver/setting related, or more accurately not bus speed related.

Questions, corrections, etc. always welcome.
Just my two cents . . .
