BIOS Shadowing The system BIOS is always copied from ROM to RAM for faster execution.
The end user can shadow 16 KB ROM segments from C0000h – DCFFFh.
IDE
The Olympus motherboard has two 40-pin IDE connectors onboard that support
up to four IDE drives (hard disk drives, CD-ROM drives, or tape drives). The
integrated PCI bus master enhanced IDE controller is on the PCI local bus. The
IDE controller supports the Ultra DMA/33 protocol, which doubles the hard
disk drive data transfer rates specified in the ATA-2 standards to 33 MB/s while
maintaining full backward compatibility with existing PIO mode 3, PIO mode 4,
and DMA mode 2 devices.
Fast ATA
The motherboard supports the Fast ATA specification using PIO mode 4 and
multiword DMA mode 2.
Ultra DMA/33 This motherboard includes an integrated enhanced IDE PCI bus master IDE
controller that supports the Ultra DMA/33 protocol. The Ultra DMA/33
protocol permits data transfer rates up to 33 MBs. Ultra DMA/33 also reduces
the CPU workload and permits increased CPU utilization. Ultra DMA/33 is
completely backward-compatible with older DMA standards.
Floppy
The Olympus motherboard has an onboard floppy controller that supports up to
two 360 KB, 720 KB, 1.2 MB, 1.44 MB, or 2.88 MB floppy drives.
Parallel Port
The Olympus motherboard has an onboard ECP and EPP-capable parallel port
connector.
Serial Ports
The Olympus motherboard has two onboard serial port connectors and two
16550 UART serial ports.
