Five 16-bit, ISA-compatible option slots Space for up to seven mass storage devices (four externally accessible and three internal) On-board support for up to two IDE hard disk drives and two diskette drives (or one diskette drive and one tape drive) Math coprocessor integrated into the DX, DX2, and Pentium microprocessors Real-time clock and calendar on main system board with built-in rechargeable battery backup. Using the built-in interfaces, you can connect most of your peripheral devices directly to the computer so you do not have to install option cards. You can use the option slots to enhance your system with extra functions such as a modem card, a network controller card, or additional interface ports. The shadow RAM feature allows your system to speed up processing by moving the system and video BIOS into the RAM area of memory. Video The local bus SVGA video interface provides data transfer at the full speed of the processor, rather than at the standard 8.33 MHz ISA bus speed. With 512KB of video RAM, the SVGA controller supports standard resolutions up to 640 x 480 in 16 colors and extended resolutions up to 640 x 480 in 256 colors or 1024 x 768 in 16 colors (interlaced and non-interlaced). With 1MB of VRAM, it supports extended resolutions up to 1280 x 1024 in 16 colors. 2 Introduction
