Module Name: src
Committed By: tsutsui
Date: Mon Aug 15 04:37:47 UTC 2022
Modified Files:
src/sys/arch/atari/pci: pci_vga.c
Log Message:
Improve VGA console settings for Milan, especially for sysinst.
- use explicit WSDISPLAY_FONTENC_IBM font that MI vga(4) assumes
(so that box drawing characters are rendered properly)
- set ATC and DAC palette settings for proper colors
(copied from MI vga_subr.c for now because HADES doesn't use mi vga(4))
Tested on Milan with S3 Trio64. (XXX: needs working HADES with ET4000)
