PRINCIPAL COMPONENTS AND FEATURES
The main features of the system board are:
• supports Pentium processors of several different clock speeds (90, 100, 120 or 133 MHz,
and 150 and 166 MHz when available) with accompanying voltage regulator module
(VRM)
• a PCI bus video controller: most models of the Vectra VL 5/xx series 4 have an integrated
64-bit Ultra VGA controller on the PCI bus (S3 Trio 765 64V+ on D3xxxA models and S3
Trio 764 on D3xxxB models)
• an Enhanced IDE controller with two channels on the PCI bus
• a primary IDE channel for two IDE hard disk drives
• a secondary IDE channel for an IDE CD-ROM drive and, in the mini-tower models, a
fourth IDE device (such as a third IDE hard disk drive)
• a combined controller on the ISA bus for
• 2 flexible disk drives and/or tape drives
• 2 serial ports
• 1 parallel port
• sockets for DRAM main memory: the Vectra VL 5/xx series 4 PCs provide six sockets for
main memory, allowing installation of up to 128 MB
• a system ROM (using flash ROM technology) that can be easily updated with the latest
firmware, using the
Phlash.exe
program supplied with the firmware upgrade. The system
ROM contains:
• the BIOS (system BIOS, video BIOS and low option ROM)
• a power-on hardware test that allows you to view the results of the diagnostics as well
as a corrective action message (error message utility)
• menu-driven SETUP with context-sensitive help (in US English only)
• a keyboard/mouse controller and interface.
