A host module is disclosed, in which an interface is used to couple to at least an electronic device through a serial bus and comprises at least first and second ports. A detection unit reports that one of the first and second ports is enabled and the other is not enabled to a serial bus host driver and enables the interface to perform data transmission with the electronic device connected to the first and second ports through two parallel transmission channels of the serial bus, when the first and second ports are both connected to the same electronic device through the serial bus.

Host modules, electronic devices, electronic systems and data transmission method thereof

A file switching method of a Basic Input/Output System (BIOS) file is disclosed. Upon a received read instruction, a timer for a predetermined timing is initiated, and a first data page having a requested data is read from a first BIOS file. An error correction check on the first data page is performed to check if any error in the first data page. If an error is occurred in the error correction check, repeating the step 'reading the first data page'. If number of times of the repeating step exceeds a predetermined number, or if the predetermined timing is expired, a second data page having the requested data is read from a second BIOS file according to the read instruction.
