Does iPXE code has any component that might change a color of the serial connection (could it be that the putty output goes black on black?)? can iPXE do that at all (change the serial output’s color)?
Yes; iPXE can output arbitrary ANSI escape sequences which can include colour change sequences. For the BIOS (or VESA framebuffer) console, these are interpreted by iPXE; for the serial console they are sent verbatim to be interpreted by the terminal software on the other end of the link.
Which INT 10 services do iPXE use for BIOS Screen Control?
All code calling INT 10 should be in arch/i386/firmware/pcbios/bios_console.c. We seem to use:
INT 10,02 : ANSI CUP INT 10,06 : ANSI ED INT 10,01 : ANSI DECTCEM and for writing characters to the screen: INT 10,08 : read current attribute INT 10,09 : set current attribute INT 10,0e : print character Michael _______________________________________________ ipxe-devel mailing list [email protected] https://lists.ipxe.org/mailman/listinfo.cgi/ipxe-devel
