Booooo! I can't get my IBM 45gig 75GXP to run ATA/100 on my Abit KT7A-Raid... I'm running win2k, and have installed the ms ata/100 patch, sp1, and all critical updates. I have installed, reinstalled the via busmaster drivers, the 4in1s many times with no help! 🙁 I'm currently using the 3.11IDE win2k drivers. The IBM is running at multiward dma mode2. Whatever the hell that is! 😛 My dvd and burner are running that the sam thing. I don't know what else to do. Anyone got any ideas?? TIA
 
Make sure your drives are set to auto detect, in the bios, not pio mode, or something like that.
Also, you may need to enable the drive for ATA100, thru a software, you get thru IBM.

And..........you do have an ATA100 cable with the blue end on the ATA100 channel, correct?
 
Yes to all of your questions. And what software to enable ata100?? Last time I isntalled Win2k it worked fine with no such software. Oh, I do have to check to make sure everything is right in the bios though. Everything is on auto-detect I know, but I dont' know about pio modes...
 
With the 686B southbridge and the MS hotfix for ATA-100, I have heard that the drive indeed is running ATA-100, but it just doesnt show up as UDMA mode in Device Manager. Supposedly a new patch, or SP2 will fix that problem.
 
dma2 is the same as ata33 the setting for ata 100 is dma5 there is a utility on IBM site called ata switch put it on a floppy and use it to boot. Follow prompts change to mode 5 and you will be set.
 
Wow, damn bios! Its fixed... I guess having default fail-safe settings selected put my DMA to disable on all devices 🙁 Fixed now though! 🙂 Thanx all
 
i have the exact same setup as you.....did all that... my hdd scores on sandra are just a little lower than an ata66 drive...🙁
 
yo2tup: i get the same score as you do, with basically the same setup. I was under the impression that Sandra HD benchmark wasnt the most accurate out there.
 
<<Wow, damn bios! Its fixed... I guess having default fail-safe settings selected put my DMA to disable on all devices Fixed now though! Thanx all>>

Windows 2000 does not support ATA-100 (Mode 5) for IDE hard disks. All ATA-100 IDE hard disks that are used with Windows 2000 default to ATA-66 (Mode 4). check
here if you don't believe me. SP2 should fix the problem.
if you must have the patch instead of SP2, then lookhere! 🙂

I have win2k installed and SiSandra and my Quantum Fireball AS is 45% higher than the udma66 hd. I know we probably have different HD but this proves that ultra ata 100 does work in win2k, I just installed the patch from Via Hardware
