BASEDEV=K6.SYS

Parameters

/V: Show screen output
/w????????: Enable first write-combine region using given hex value
/W????????: Enable second write-combine region using given hex value

Sample

BASEDEV=K6.SYS /V /w??01FE02

where ?? is the leading two hex digits of the video memory's physical address.

Remarks

TIP: See also WACKER.SYS which is recommended by users.
