59 | The Extended Industry Standard Architecture (EISA) bus was | |
60 | developed as an open alternative to the IBM MicroChannel bus. | |
61 | ||
62 | The EISA bus provided some of the features of the IBM MicroChannel | |
63 | bus while maintaining backward compatibility with cards made for | |
64 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
65 | 1995 when it was made obsolete by the PCI bus. | |

900 | On some architectures (EBSA110 and CATS), there is currently no way | |
901 | for the boot loader to pass arguments to the kernel. For these | |

909 | help | |
910 | Execute-In-Place allows the kernel to run from non-volatile storage | |
911 | directly addressable by the CPU, such as NOR flash. This saves RAM | |
912 | space since the text section of the kernel is not loaded from flash | |
913 | to RAM. Read-write sections, such as the data section and stack, | |
914 | are still copied to RAM. The XIP kernel is not compressed since | |
915 | it has to run directly from flash, so it will take more space to | |
916 | store it. The flash address used to link the kernel object files, | |
917 | and for storing it, is configuration dependent. Therefore, if you | |
918 | say Y here, you must know the proper physical address where to | |
919 | store the kernel image depending on your own flash memory usage. | |

921 | Also note that the make target becomes "make xipImage" rather than | |
922 | "make zImage" or "make Image". The final kernel binary to put in | |
