Hard Disk Block Mode; Advanced Pio Mode; Hard Disk Size > 504 Mb; Hard Disk 32-Bit Access - Acer Altos 9100B User Manual

Hard Disk Block Mode

This function enhances disk performance depending on the hard disk in use. If
you set this parameter to Auto, the BIOS utility automatically detects if the
installed hard disk drive supports the Block Mode function. If supported, it
allows data transfer in block (multiple sectors) at a rate of 256 bytes per cycle. To
disregard the feature, change the setting to Disabled.

Advanced PIO Mode

When set to Auto, the BIOS utility automatically detects if the installed hard disk
supports the function. If supported, it allows for faster data recovery and
read/write timing that reduces hard disk activity time. This results in better hard
disk performance. To disregard the feature, change the setting to Disabled.
Hard Disk Size > 504 MB
When set to Auto, the BIOS utility automatically detects if the installed hard disk
supports the function. If supported, it allows you to use a hard disk with a
capacity of more than 504 MB. This is made possible through the Logical Block
Address (LBA) mode translation. However, this enhanced IDE feature works
only under DOS and Windows 3.x, Windows 95 environments. Other operating
systems require this parameter to be set to Disabled.

Hard Disk 32-bit Access

Enabling this parameter improves system performance by allowing the use of the
32-bit hard disk access. This enhanced IDE feature works only under DOS,
Windows 3.x, Windows 95, and Novell NetWare. If your software or hard disk
does not support this function, set this parameter to Disabled.

CD-ROM Drive DMA Mode

This parameter allows you to enable or disable the CD-ROM drive DMA mode.
Set this parameter to Enabled to enable the DMA mode for the CD-ROM drive.
