- Introduction.
-
- These files are what I have been able to collect of information on
- the various Super VGA cards and other display adapters.
- The information should be regarded with a healthy dose of sceptism
- as I have been unable to test most of it.
- Hopefully it will be of use to you all.
-
-
- Terminology/style:
-
- The BIOS calls are mostly taken directly from Ralf's interrupt list
- and tends to follow its style and structure.
-
- The register descriptions are sorted by the register number.
-
- All register addresses, data values etc are given in hexadecimal.
-
- 3d4h means 3D4h when in color mode and 3B4h when in monochrome mode.
-
- 3CEh index 3 means register 3CEh is set to 3 and register 3CFh is the
- data port. See notes on register 3C0h under VGA registers.
- On some cards write operations can be done with a single OUTW
- instruction. This may fail on some cards or machines.
- ATI cards require the index to be updated before each access to
- the dataport.
-
- (R) means the register is Read Only.
- (W) means the register is Write Only.
- (R/W) means the register is both Readable and Writable.
- (r/W) means the register is Write Only on EGA cards and Read/Writable
- on VGA cards.
-
-
- The examples are in Turbo Pascal for readability.
- For non Turbo users $1234 is hex 01234h and port[$3cd]:= is an OUT
- to register 03CDh and port[$3cd] (in an expression) is an IN from
- register 03CDh.
