I have a commercial program (the registered version of GEOCLOCK 4.2, for the
curious) that has the ability to put the screen in Super VGA mode
(800x600x16). It does this by setting up the Ax and Bx (and Cx and Dx)
registers and making a call to INT 10. The documentation reads as follows:
SVGA -CGE SVGAa/b/c/d enables SVGA (800x600) display. If this command
is not included in the GECONFIG.DAT file, SVGA maps may not
be displayed. The arguments indicate the values to be
loaded into the AX, BX, CX, and DX registers before the call
to INT 10 to enter SVGA mode. For the Paradise SVGA, the
parameters are optional: SVGA88/0/0/0 is assumed. Check
with you display adapter supplier if you are not sure of the
correct parameters to use. (Tell your supplier than you
need the decimal values for the registers to enter the
800x600x16 mode using INT 10). DO NOT include this command
unless you have a super VGA adapter and a multisync monitor:
your monitor may be damaged if it does not support the
vertical and horizontal frequencies generated by the SVGA.
I have a Northgate Slimline which uses the ZyMOS "Poach" chipset. I tried
calling Northgate to get the values for the registers, but they didn't give
me a good answer. They also didn't have ZyMOS's telephone number. So can
anyone provide me with information on how to get a hold of ZyMOS? I tried
calling 1-800-directory-assistance, but there was no listing, as well as no
listing in the Los Angeles area.
Thanks - Jim
