 This is a pre-release of the VGA3 support codes. The keyboard emulates a TTY, returning 7-bit ASCII codes normally, and specific 8-bit codes for the extended 104/105 PS/2 keyboard. These extended codes are compatible with RomWBW, but will display as oddball ASCII by CP/M, which masks all input to 7-bits. NumLock, CapsLock, and ScrollLock lights are enabled. The first two operate as expected, and I am considering implementing ScrollLock as an End-of-Line XON/XOFF – which I think IBM may have intended from the outset. Coments would be welcome. This is a pre-release of the VGA3 support codes.

 When you upgrade the BIOS, do not forget that UNA will boot with a delay of 10-15 seconds as it searches for the console device. When you upgrade the BIOS, do not forget that UNA will boot with a delay of 10-15 seconds as it searches for the console device.

 NOTE: The first time you boot a new UNA release, there is a 10 second delay while it auto-detects the console. This delay will also be experienced if you request a "Full Init" from the setup menu. The "Full Init" is only required if you are changing ROM's, or changing consoles. NOTE: The first time you boot a new UNA release, there is a 10 second delay while it auto-detects the console.
