| 1. Overview |
| VESA VBE/Core 2.0 is an extension of the VESA VBE 1.2 standard (VBE = Video BIOS Extension). |
| S3 VBE/Core 2.0 is a MS-DOS TSR program, which installs a VESA VBE/Core 2.0 for S3 graphics cards with a VESA VBE 1.2. |
| S3 VBE/Core 2.0 supports the following S3 graphics chips: Vision864, Vision868, Vision964, Vision968, Trio32, Trio64, Trio64V+, Trio64UV+, Trio64V2/DX, Trio64V2/GX, ViRGE, ViRGE/VX, ViRGE/DX, ViRGE/GX. |
| 2. Installation |
| Type "S3VBE20 /?" to display a help screen. |
| One way to install S3 VBE/Core 2.0 on your system is to unzip S3VBE318.ZIP to the directory C:\S3VBE20 and insert the line |
|
C:\S3VBE20\S3VBE20 /INSTALL |
| in your AUTOEXEC.BAT. |
| 3. Low resolution video modes |
| S3 VBE/Core 2.0 provides the following low resolution video modes: |
| 320 x 200 x 8 @ 70 Hz, |
| 320 x 240 x 8 @ 68 Hz, |
| 320 x 400 x 8 @ 70 Hz, |
| 320 x 480 x 8 @ 68 Hz, |
| 400 x 300 x 8 @ 74 Hz, |
| 512 x 384 x 8 @ 82 Hz. |
| If the original video BIOS supports VBE mode 10Dh (320x200x15) and 10Eh (320x200x16), S3 VBE/Core 2.0 provides two additional video modes: |
| 320 x 240 x 15, |
| 320 x 240 x 16. |
| Since these low resolution modes use non-standard CRT parameters there is a remote possibility that these modes may not work or may damage defective monitors. |
| 4. Known problems |
| There may be problems when using VESA VBE/Core 2.0 linear frame buffer modes under Windows 95 with a Trio64V+ graphics chip. |
| These problems can be solved by disabling screen clears during VBE mode sets. Type "S3VBE20 CLEAR-" to disable screen clears during VBE mode sets. Most applications will write their own image into video memory and don't really need a screen clear. |
