PowerMate Pro150 System
1-5
The system supports up to six drives. The system ships with one 1.44 MB
diskette drive installed in the 3.5-inch bay. The 5.25-inch bay can hold up to
three half-height 5.25-inch drives. The 3.5-inch drive bay can hold up to
three 3.5-inch drives.
If you are using third-party controllers or non-IDE hard disk drives, each of
the controller functions can be disabled in Setup (Chapter 3).
System BIOS
The system BIOS, from American Megatrends Incorporated (AMI), provides
ISA and PCI compatibility. The BIOS is contained in a flash memory device
on the system board. The BIOS provides the power-on self test (POST), the
system Setup program, a PCI and IDE auto-configuration utility, and BIOS
recovery code. Note that Power Management is not supported.
The system BIOS is always shadowed. Shadowing allows any BIOS
routines to be executed from fast 32-bit onboard DRAM instead of from the
slower 8-bit flash device.
PCI Auto-configuration
The PCI auto-configuration utility works in conjunction with the Setup
program to support using PCI add-in boards in the system. When you turn
on the system power after installing a PCI board, the BIOS automatically
configures interrupts, DMA channels, I/O space, and so on. Since PCI add-
in boards use the same interrupt resources as ISA add-in boards, you must
specify the interrupts used by ISA boards in the Setup program. Chapter 3
tells how to use the Setup program. The PCI auto-configuration program
complies with version 2.1 of the PCI BIOS specification.
IDE Auto-configuration
If you install an IDE drive in the system, the IDE auto-configuration utility
automatically detects and configures the drive for operation in the system.
This utility eliminates the need to enter the Setup program after you install
an IDE drive.
