6.13.3 Limitations

Console redirection is a real-mode BIOS extension. It does not operate outside of real mode. In

addition, console redirection will not function if the operating system or a driver, such as

EMM386*, takes the processor into protected mode. If an application moves the processor in

and out of protected mode, it should inhibit redirection before entering protected mode and

restart redirection when it returns to real mode.

Video is redirected by scanning and sending changes in text video memory. Therefore, console

redirection is unable to redirect video in graphics mode. Since the BIOS scans the text video

memory, an additional limitation exists if the system does not contain a video graphics adapter

or a proprietary means of buffering the video memory. The BIOS may not have a method to

send changes in text video memory if an application such as an option ROM writes directly to

video memory.
