_VIDEO_X86_BIOS_ARGUMENTS structure

Description

The VIDEO_x86_BIOS_ARGUMENTS structure is used to support full-screen MS-DOS application INT10 calls. It contains seven of the high-end x86 microprocessor registers.

Members

`Eax`

`Ebx`

`Ecx`

`Edx`

`Esi`

`Edi`

`Ebp`

Are the seven x86 microprocessor registers.

Remarks

MS-DOS INT10s are usually "set mode" requests for the video adapter. Each value is put in the appropriate register and an INT10 call is performed by VideoPortInt10.

A miniport driver should not set a segment:offset-type pointer in any member of this structure. Such an address is interpreted as an unsigned DWORD value.
