| 493 | There are two different types of booting firmware on Alphas: SRM, |
| 494 | which is command line driven, and ARC, which uses menus and arrow |
| 495 | keys. Details about the Linux/Alpha booting process are contained in |
| 496 | the Linux/Alpha FAQ, accessible on the WWW from |
| 497 | <http://www.alphalinux.org/>. |
| 498 | |
| 499 | The usual way to load Linux on an Alpha machine is to use MILO |
| 500 | (a bootloader that lets you pass command line parameters to the |
| 501 | kernel just like lilo does for the x86 architecture) which can be |
| 502 | loaded either from ARC or can be installed directly as a permanent |
| 503 | firmware replacement from floppy (which requires changing a certain |
| 504 | jumper on the motherboard). If you want to do either of these, say N |
| 505 | here. If MILO doesn't work on your system (true for Jensen |
| 506 | motherboards), you can bypass it altogether and boot Linux directly |
| 507 | from an SRM console; say Y here in order to do that. Note that you |
| 508 | won't be able to boot from an IDE disk using SRM. |
| 509 | |

| 641 | (or if you intend to compile a generic kernel). It will simply |
