IDE HDD Block Mode
Block mode is also called block transfer, multiple commands, or multiple
sector read/write. If your IDE hard drive supports block mode (most new
drives do), select Enabled for automatic detection of the optimal number
of block read/writes per sector the drive can support. The settings are:
Enabled (Default), Disabled.
On-Chip Primary/Secondary PCI IDE
The integrated peripheral controller contains an IDE interface with sup-
port for two IDE channels. Select Enabled to activate each channel sepa-
rately. The settings are: Enabled (Default) and Disabled.
IDE Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields let you set a PIO
mode (0-4) for each of the four IDE devices that the onboard IDE inter-
face supports. Modes 0 through 4 provide successively increased perfor-
mance. In Auto mode, the system automatically determines the best mode
for each device. The settings are: Auto (Default), Mode 0, Mode 1, Mode
2, Mode 3, Mode 4.
