Hello All, Right now I am involved in developement of a PC BIOS which works fine when all output is sent to the serial port. I am even able to tftp load binaries, including OS binaries and execute them.
My next concern now is to get BIOS messages out to the Video instead of the serial port. I just want the regular text mode 25X80 output and nothing fancy. I want to know what I need to do to get text frame buffer working at b800:0000 working. Do I absolutely need to call VGA BIOS init to get this working? Right now with my BIOS, the monitor does not stop blinking its orange light and writes to b800:0 do not produce anything, but when I insert an Award BIOS chip, I get this blinking of monitor for some time and then it suddenly comes alive with a beep and a green light. I am wondering what does Award BIOS do to achieve this or is it just calling VGA BIOS init? If someone has a code snippet or a pointer to one or just a broad outline to what needs to be done, I will appreciate it very much.
