Incompatible Windows 3.0 ATI Video Drivers

• Microsoft Windows operating system versions 3.0, 3.0a

SUMMARY

ATI Technologies has reported that the following two ATI video drivers do not work properly with Microsoft Windows version 3.0 and should be removed from the CONFIG.SYS file:

• ATIVIDEO.SYS
• ROMBIOS.SYS

MORE INFORMATION

ATI uses the drivers ATIVIDEO.SYS and ROMBIOS.SYS to shadow the video BIOS from read only memory (ROM) into random access memory (RAM)

Video or ROM shadowing is when the instructions contained on the ROM chip are copied to the RAM chip at bootup. Accessing RAM is faster than accessing ROM, and shadowing the video BIOS into RAM increases the speed of the screen writes.

ATI recommends taking these drivers out of CONFIG.SYS for other reasons, also. If you have a 286 or 386 system, your machine may have the capability to provide these features in the system setup of your machine. This procedure does not use valuable conventional memory for these settings such as loading the drivers in the CONFIG.SYS does.
