Search for a key called MasterDeviceTimingMode in the registry (dword). If it is there the values are: 0x10010 UDMA Mode 5 (ATA100). 0x8010 UDMA Mode 4 (ATA66). 0x2010 UDMA Mode 2 (ATA33). 0x0410 Multi-Word DMA Mode 2 и PIO 4.

Intel Application Accelerator lets you set the mode, double click on the items in the parameters column. If it only allows you to set modes for UDMA2 and lower you can force the mode via regedit under the correct key (I did this on Win98 years ago to force a drive to UDMA 2 from PIO mode). To find …

One thing I'm curious about is the cluster size from oformat, I saw in the documentation it defaults to 8 (4kb) but you can set it to 128 (64kb) which could improve read speeds at the cost of a little more space consumed but that doesnt matter too much on these much larger drives, what do you think …

I think actually the PATCH1TB isn't for the OS drive/partition, but a secondary drive/partition. Maybe though it will work on the OS drive, secondary partition, the manual doesn't mention this but maybe that's what it is. I'll do another installation and test this and report back. If this fails …

I think the DMA mode is depend on which bridge chip is on the adapter board i have good result with JMicron JM20330 bridge if your adapter is using sanded down chip or sunplus then they may cause DMA issue. I ruled out adapters 100% by connecting the SSDs directly to newer chipsets with native sata …

I can 'cause' coil whine by using the 'throttle.exe' utility on my MS6156 (440BX chipset). It uses ACPI CPU throttling feature in slowdown steps of 8. To stop the whine I wedged a rubber (any insulator) slightly against the inductor with a ferrite core.

Speaking of which, General MIDI works by using ECW sets for the softsynth, which is Ensoniq's proprietary format. The driver CD contains three sets in total: 2MB, 4MB and 8MB with the last one arguably providing the best quality. You can switch between these sets from the driver panel at any time. …

Haha, FM emulation was terrible on these. I think this emulator was later reused and improved for the Live! series of cards, though I don't think it ever sounded pleasant. Couldn't you fix that by always selecting Adlib or OPL2 in games' setup options instead of SB16 or OPL3. I think I remember …
