(Windows 95 OSR2 or a third-party IDE bus master driver). If your hard
drive and your system software both support Ultra DMA/33, Ultra DMA/
66 and Ultra DMA/100 select Auto to enable BIOS support. The settings
are: Auto, Disabled.
IDE Prefetch Mode
The onboard IDE drive interfaces support IDE prefetching, for faster
drive accesses. When you install a primary and/or secondary add-in IDE
interface, set this option to Disabled if the interface does not support
prefetching.
IDE DMA Transfer Access
This item is used to enable or disable the DMA transfer function of the
IDE Hard Drive. The settings are: Enabled, Disabled.

Block mode is also called block transfer, multiple commands, or mul-

number of block read/writes per sector the drive can support. Settings:
Enabled, Disabled.
