Enable/ disable zero-wait state
J1 allows you to enable/disable the adapter’s
ISA bus zero-wait state feature. When enable
(default), the CPU can transfer data to the
VGA adapter at the zero-wait state rate through ISA bus. If your display exhibits pixel dropouts or the system hangs, use Jumper J1 to disable the zero-wait state stage.

Select Scan Rate: J7
7 allows you to configure the scan rates of extend VGA odes to be compatible with your multi-scanning monitor. J7 is operational for 512K and 1MB configurations only. If your monitor can scan at 48.7KHz, remove the Jumper pin across
J7. J7 in the open position will allow non-interlaced display for
1024x768 modes and higher horizontal and vertical scan rates for 800x600-16 color (i) and 800x600-256(ii). If your monitor cannot scan at 48.7 KHz, leave the Jumper pin for J7 in the default position. This will give interlaced display for 1024x768 modes and reduced horizontal and vertical scan rates for the
800x600-16 color (i) and 800x600-256 (ii).
NOTE: (i) Supported by 512KB and 1024KB memory.
(ii) Only supported by 1024 KB memory.

Enabled/Disabled Auto detect: J8
J8 allows you to enable/disable the BIOS Auto detect feature. When enable (default), the BIOS will determine whether the Graphics Adapter can operate with an 8-bit o 16-bit BIOS interface accordingly. When disabled, the board will boot up in its BIOS interlace setting (generally 8-bit).
NOTE: If you have problems booting your system, set
Jumper J8
