Devices on the PCI Bus
S3 Trio 64PnP Video Controller
The integrated video subsystem consists of a PCI bus video controller and a
DRAM array. The PC uses the S3 Trio 64 PnP video controller. This video
controller embeds a RAMDAC, and supports video resolutions of up to 1280
x 1024. The S3 Trio 64PnP video controller offers full compatibility with
VGA. In addition, the features are enhanced beyond Super VGA by
hardware which accelerates graphical user interface operation in
Windows 95.
The enhanced features include:
• Direct connectivity to PCI bus.
• True acceleration for 8, 16 and 32-bit pixel depths.
• 57 MHz clock for video memory.
• Fully programmable Pixel Clock Generator up to 135 MHz.
• Availability to support 2 MB DRAM.
• Fast linear addressing with full software relocation.
Video DRAM
The HP Vectra 500 Series PC is supplied with 1 MB of video DRAM. An
additional 1 MB of video DRAM can be installed. The upgrade consists of
two 512 KB video memory chips.
Video Resolutions Supported
For a full list of the different video resolutions available, refer to “S3 Trio 64
Video Modes” on page 121, for a table containing all the supported video
resolutions.
Integrated Drive Electronics (IDE) Controller
The IDE controller is implemented as part of the PCI/ISA bridge chip (see
page 65). It supports Enhanced IDE (EIDE) and Standard IDE (Bus Master
IDE). To use the Enhanced IDE features, however, hard disk drives must be
compliant with Enhanced IDE.
Up to four IDE devices can be supported: two connected to the primary
channel cable, and two to the secondary channel cable. For minitower
models, the primary and secondary channels are both fitted with IDE cables
