23 | The ARM series is a line of low-power-consumption RISC chip designs | |
f6c8965a | 24 | licensed by ARM Ltd and targeted at embedded applications and |
1da177e4 | 25 | handhelds such as the Compaq IPAQ. ARM-based PCs are no longer |
f6c8965a | 26 | manufactured, but legacy ARM-based PC hardware remains popular in |
1da177e4 LT |
27 | Europe. There is an ARM Linux project with a web page at |

64 | The Extended Industry Standard Architecture (EISA) bus was | |
65 | developed as an open alternative to the IBM MicroChannel bus. | |
66 | ||
67 | The EISA bus provided some of the features of the IBM MicroChannel | |
68 | bus while maintaining backward compatibility with cards made for | |
69 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
70 | 1995 when it was made obsolete by the PCI bus. | |

988 | Execute-In-Place allows the kernel to run from non-volatile storage | |

991 | to RAM. Read-write sections, such as the data section and stack, | |
992 | are still copied to RAM. The XIP kernel is not compressed since | |
993 | it has to run directly from flash, so it will take more space to | |
