0013 The 2.4 kernel changed the kernel start address from 0x310000
0014 to 0x810000 to make room for the Wildfire's larger SRM console.
0015 Recent consoles on Titan and Marvel machines also require the
0016 extra room.

0018 If you're using aboot 0.7 or later, the bootloader will examine the
0019 ELF headers to determine where to transfer control. Unfortunately,
0020 most older bootloaders -- APB or MILO -- hardcoded the kernel start
0021 address rather than examining the ELF headers, and the result is a
0022 hard lockup.

0024 Say Y if you have a broken bootloader. Say N if you do not, or if
0025 you wish to run on Wildfire, Titan, or Marvel.

0036 This option is required for IEEE compliant floating point arithmetic
0037 on the Alpha. The only time you would ever not say Y is to say M in
0038 order to debug the code. Say Y unless you know what you are doing.
