Methods and apparatus to enable console redirection in a multiple execution environment
Methods and apparatus to enable console redirection in a multiple execution environment are disclosed. In an example method, at least one periodic interrupt in a first basic input/output system (BIOS) execution environment of a local console is initiated. Data associated with a second BIOS execution environment of the local console is retrieved. The data associated with the second BIOS execution environment is communicated to a remote terminal.

11. A machine readable medium as defined in claim 9 , wherein the instructions cause the machine to initiate the periodic interrupt in the first BIOS execution environment of the local console by initiating the periodic interrupt in an extensible firmware interface (EFI) environment of the local console.
12. A machine readable medium as defined in claim 9 , wherein the instructions cause the machine to retrieve data associated with the second BIOS execution environment of the local console by retrieving data associated with a 16-bit code environment of the local console.
13. A machine readable medium as defined in claim 9 , wherein the instructions cause the machine to retrieve data associated with the second BIOS execution environment of the local console by retrieving data associated with at least one of a keyboard input, a mouse input, and a video output of the local console.
14. A machine readable medium as defined in claim 9 , wherein the console redirection comprises at least one of text console redirection, graphics console redirection, keyboard console redirection, and mouse console redirection.
15. A machine readable medium as defined in claim 9 further comprising instructions, which when executed, cause a machine to terminate the at least one periodic interrupt in response to terminating operation in the second BIOS execution environment.
16. A machine readable medium as defined in claim 9 , wherein the machine readable medium comprises one of a programmable gate array, application specific integrated circuit, erasable programmable read only memory, read only memory, random access memory, magnetic media, and optical media.
