2.4 BIOS
The BIOS on the AI5TV system board provides the standard BIOS
functions plus the following additional features:
1. ISA Plug and Play (PnP) extension
Unlike PCI cards which are plug and play, ISA cards require setting
jumpers to resolve hardware conflict. To make a computer system
PnP, an ISA PnP standard is established and supported by new OSes,
such as Windows 95. Under Windows 95, the system board BIOS
must have ISA PnP extension to support the new ISA PnP cards.
2. Power management
The power management feature provides power saving by slowing
down the CPU clock, turning off the monitor screen, and stopping
the HDD spindle motor.
3. NCR 53C810(AHA7850) SCSI BIOS
NCR 53C810(AHA7850) is a PCI SCSI shipped from NCR
(Adaptec). The BIOS required to run cards with the
53C810(AHA7850) chip is built-in the system BIOS. The BIOS will
automatically detect the existence of an 53C810 (AHA7850) chip
and configure it accordingly.
