Big problem. My hard drive can't access DMA, although my CD-writer can. Hard drive is currently in PIO mode 4 (stinks). My hard drive can barely supply enough data to write at 4x!. It's a 10GB IBM drive, UDMA/66. On a (I think) matshita board with the SiS 730s chipset. Help me! I believe it may be an incompatibility with Windows 2000 (it's not MS's fault this time, the OS came out before the chipset). Sis FAQ actually has something about it, though it is a bit cryptic.
- In SiS desktop products ( SiS 5598, 5591, 5600, 530, 620, 540, 630...), how to enable DMA mode under NT 4.0 ? And how to enable DMA mode in Windows 2000 professional?
A: (1).First, please install NT 4.0 Service Pack 6, then execute the following steps to enable DMA:
Execute the DMACHECK.EXE program on the Windows NT 4.0 Service Pack 6 (SP6) CD from the \support\utils\i386\ directory. DMACHECK.EXE will indicate if DMA is enabled on the primary or secondary IDE channel. Click the Enabled option to enable DMA for the UDMA-capable hard drive.
Reboot the system. Execute the DMACHECK.EXE program again to verify that DMA was successfully enabled.
(2)In order to enable the DMA mode in Windows 2000, please make sure that the ASL code has been implemented in system Bios or not. You may contact the board maker to get the details.
I did a little research and the ASL code is ACPI System Language or something related to ACPI. ACPI is enabled, installed, but nothing. And no, Installing Windows 98 is not an option, this is a shared computer and I need it stable.
If anyone has a solution, PLEASE respond.
