  412. There are two different types of booting firmware on Alphas: SRM,
  413. which is command line driven, and ARC, which uses menus and arrow
  414. keys. Details about the Linux/Alpha booting process are contained in
  415. the Linux/Alpha FAQ, accessible on the WWW from
  416. <http://www.alphalinux.org/>.
  417. The usual way to load Linux on an Alpha machine is to use MILO
  418. (a bootloader that lets you pass command line parameters to the
  419. kernel just like lilo does for the x86 architecture) which can be
  420. loaded either from ARC or can be installed directly as a permanent
  421. firmware replacement from floppy (which requires changing a certain
  422. jumper on the motherboard). If you want to do either of these, say N
  423. here. If MILO doesn't work on your system (true for Jensen
  424. motherboards), you can bypass it altogether and boot Linux directly
  425. from an SRM console; say Y here in order to do that. Note that you
  426. won't be able to boot from an IDE disk using SRM.
  427. If unsure, say N.
