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)
