I need to have access to the VGA port and register. The register I need access in the range of 0x300 to 0x400 so I try getting a 1KB page from 300 onward, but it do not work. I suspect it do not work because it is I/O FPage and they have to align to (in this case 1kB) address. Could anyone help me access these port?
