| 35 | It is a binary blob which U-Boot uses to set up SDRAM. |

| 61 | Virtual Machine Extensions are provided in many x86 CPUs. These |
| 62 | provide various facilities for allowing a host OS to provide an |
| 63 | environment where potentially several guest OSes have only |
| 64 | limited access to the underlying hardware. This is achieved |
| 65 | without resorting to software trapping and/or instruction set |
| 66 | emulation (which would be very slow). |
| 67 | |
| 68 | Intel's implementation of this is called VT-x. This option enables |
| 69 | VT-x this so that the OS that is booted by U-Boot can make use of |
| 70 | these facilities. If this option is not enabled, then the host OS |
| 71 | will be unable to support virtualisation, or it will run very |
| 72 | slowly. |
