DMA modes
In BIOS, my CD burners are set to PIO mode 4 and DMA mode 2. DMA mode 4 is
also available. Is there any advantage to switching to DMA 4 in BIOS? The IDE controller, both channels, are set to UDMA in Windows 2000. -JasonW |
BIOS setting has no influence on what Windows is using. Windows controls the
hardware directly, not through the BIOS. There are some exceptions, but for standard IDE this is always the case. The BIOS settings just change how the system accesses the drives during BOOT. Setting to "Auto" is usually the best option. M. In BIOS, my CD burners are set to PIO mode 4 and DMA mode 2. DMA mode 4 is also available. Is there any advantage to switching to DMA 4 in BIOS?
