win2k and ATA100

[Sixpac]

I searched the site but couldn't find anything... anyways...

Is there a registry entry to enable ATA100 on Windows 2000? If so where can I find it.

Thanks!!!!

If what you're having trbl with is having Win2K recognize your ATA100 HD, here is your solution. 1.Create a copy of the win2k boot up disks(you'll need 4 disks). 2.create a disk or get the ata100 driver diskette for your HD. 3.Boot your system using the win2k disk1. 4.watch the bottom of the screen when the system is loading disk 1 and it will prompt you to press F6 to add scsi drive... 5. After the press F6 prompt disappears continue to follow intructions, after you load up disk 3 the system will ask you to insert the ATA100 or scsi HD driver disk. If you follow instructions from this point on the rest should be a breeze....Well I hope this helped. http://www.sysopt.com/forum/smile.gif

Sorry that is not what I meant. The system is running fine. But I have heard they are reg fix's to enable ATA100 once you have windows loaded. It optimizes windows while runnin ATA100 IDE.

Please excuse my ignorance, this is probably a stupid question but...I am running Win2k & have several ATA100 drives. How can I verify whether they defaulted to 66 ?

"Enable ATA/UDMA 66 support, assuming your hard drive(s) supports it that is. By default in Windows 2000, support for ATA/UDMA66 is disabled (On Intel chipsets at least). Click on Start, Run, type in regedit & hit Enter. Go to [HKEY_LOCAL_MACHINE\System\CurrentControlSet\
Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}
\0000]. Add a New DWORD value entitled EnableUDMA66 & give it a value of 1 to enable support for UDMA/ATA 66, 0 disables it. This can greatly improve hard drive performance if supported, remember the Page file is located on your hard drive(s) too; the faster the data transfers the faster your Page File is. NOTE – This is not the same as enabling DMA support as shown previously."........... http://www.3dspotlight.com/tweaks/memory-win2k/memory-2.shtml not for Ata 100 but...

Q260233 Support for ATA 100 (Mode 5) in Windows 2000 one of many fixes in SP-2. I read somewhere thats its getting released in a week or 2.
