PC kernel The PC kernel is currently being updated to bring it up-to-date with Plan 9 support (the original Inferno PC kernel was derived from an extended subset of an earlier edition of Plan 9). In particular, although it can be configured as a server, graphics support is still being provided. (The kernel level code in vga*.c, devvga.c and screen.c is probably near the final version, but some Limbo code is needed to set the right graphics modes.)
