I have a Western Digital Hard Drive that is UDMA capable (just the old regular UDMA33, not the new 66 version). Specs say it is, boot up messages give me all the right info, regarding UDMA and bus mastering, thus I know it's UDMA capable and the BIOS is detecting it as such. I checked in Device Manager under Win 98 and under Hard Disk Controller I do see "Intel 82371AB/EB PCI Bus Master IDE Controller" present. I looked under the Settings tab of the hard disk properties window in Device Manager and the DMA box was visible but not checked. I checked it and rebooted and it stayed checked. Questions:
1.) Does this mean I now have UDMA completely enabled in Win 98
2.) Is this proper way of enabling everyhting that I need to enable to make sure UDMA is active; did I miss anything
3.) How do I really know that UDMA is working? I mean the hard drive works fine, etc. and for the most part I don't see any differences. And I did some very crude comparisons tests, eg. Windows boot up time (probably not the best I guess). Anyhow, the times were the same whether the DMA box was checked or not.
4.) Is there a way to check to see if UDMA is working, in Win 98, and/or 3rd party utility.
5.) I understand this a point of contention, whether to check the DMA box or not? Opinions?
Thanks for your help; I appreciate it.
