Super I/O

The Super I/O board is a feature of Development Kits. The board is build around a SMSC LPC47M157 chip. A datasheet for a close relative can be found at http://datasheet.seekic.com/PdfFile/LPC/LPC47M140NC_SMSC_SMSC_Corporation.pdf (a working link seems to be: http://pdf-file.ic37.com/pdf1/SMSC/LPC47M140_datasheet_138298/225601/LPC47M140_datasheet.pdf)

The board provides the following ports:

• RS232 (used for Kernel debugging, not the same as Xbox Debug Monitor)

unpopulated ports or functions are:

• PS2 mouse and keyboard^{[citation needed]}
• something MCPX (SMBus?)^{[citation needed]}
• Temp something (SMBus?)^{[citation needed]}
• Post code (SMBus?)^{[citation needed]}
• Flashrom bios (like modchips, replaces onboard kernel?)^{[citation needed]}
