PC AT
Next186_220217.rbf

He recopilado varias imágenes de Next186.vhd y ninguna me ha funcionado.
Todas se quedan colgadas esperando después de cargar la ROM.
Tampoco he conseguido que el core funcione instalando el MSDOS directamente en la SD.

Lo único que de momento me ha funcionado es esta imagen:

Si alguien tiene idea de por que los otros ficheros vhd no funcionan estaría bien que lo explicara.

PC AT

- Cache/VGA coherency changes - lot less cache flushes
- More speed options
- CGA mode support (BIOS modes 04h, 05h, 06h)
Note: BIOS functions are missing to write text in graphics modes
