(such as the DOS dvorak driver) but then returned a result to the standard controller that says "this is an invalid key" or a similar response. > KBD: controller passed byte f2h to keyboard Scan code f2h is not a valid key... and also, it isn't a valid status control code either. > KBD: indentify keyboard command received doesn't seem to like keyboard identify commands? > vga_update(): updated=0 enabled=1 > vga_update(): updated=0 enabled=1 > vga_update(): updated=0 enabled=1 These look fine to me, I don't think it's an error.. just a message. > int10h: f 1A, sf 0: returning hardcoded result Ok: Int 10, AH = 1A is "AT BIOS Video Services", "Display Combination" My documentatino mentions it as supported on the PS, VGA, and MCGA BIOS's. What's going on is Microsoft is trying to figure out if you want color or mono by detecting what type of monitor you have. > unsupported IO read from port 56e0 > unsupported IO read from port aae0 > unsupported IO read from port e2e0 > unsupported IO read from port 1ee0 These ports aren't anything I know of. Possibly a hardware probe for some card? > int10h: f 12h: sf 34h > bochs: panic, int10h: f 12h: subf BL=34h Int 10, AH = 12, BL = 34 : "AT BIOS video Services", "Alternate Function Select - Cursor Emulation." listed as supported under the VGA BIOS. it Enables/Disables alphanumeric cursor emulation. I think they are trying to turn the cursor off. > real mode > CS.d_b = 16 bit > current operand size = 16 > current address size = 16 > SS.d_b = 16 bit =) more messages, not error it looks like.
