NAME

ibm8514 − IBM 8514/A Display adapter for the ibm8514, ibm8604, ibm85xx

SYNOPSIS

pseudo-device ibmvbarmmmdxiv

DESCRIPTION

The IBM 8514/A display adapter is an optional adapter card for the IBM PS/2.  It is capable of driving all displays available for the VGA (see vga(4)). 

In the advanced function mode, IBM 8514/A adapter with the IBM 8514/A Display can display 1024 x 768, 256 colors out of a palette of 256,000.  In VGA emulation mode, the ibm8514/A adapter mirrors what is displayed on the VGA screen. 

In window manager mode, bufemul(4) supplies an ioctl that initializes the 8514/A to advanced function mode.  There is no documented interface to the 8514/A advanced function mode. 

The kernel initializes the 8514/A into the advanced function mode and then drives the display as an 80x42 character display in glass tty mode. 

NOTES

Ibm8514 is not supported on the IBM RT PC Academic System. 

DIAGNOSTICS

None.
