Epson Printer VGA Drivers

On-board support for up to two IDE hard disk drives and two diskette drives (or one diskette drive and one tape drive)

Real-time clock and calendar on main system board with built-in rechargeable battery backup.

The 486SLC microprocessor in this computer is i486SX instruction set compatible. It features a 32-bit internal/16-bit external data path.

The shadow RAM feature speeds up processing by moving the system and video BIOS into the RAM area of memory.

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 local bus video interface provides data transfer at the full speed of the processor, rather than at the standard 8.33 MHz ISA bus speed.

VGA Drivers

Your computer comes with VGA drivers and utilities for use with the integrated video interface. With these drivers, you can take advantage of the extended VGA features such as higher resolutions and 132-column text mode when you run popular applications. If yours system was configured for you, these drivers and utilities may be installed on your hard disk. If you need to install them yourself, see the instructions in Chapter 1. To obtain drivers for additional applications, call the EPSON ConnectionSM access the Epson America Forum on CompuServe. ®
