| 13 | The 2.4 kernel changed the kernel start address from 0x310000 |
| 14 | to 0x810000 to make room for the Wildfire's larger SRM console. |
| 15 | Recent consoles on Titan and Marvel machines also require the |

| 18 | If you're using aboot 0.7 or later, the bootloader will examine the |
| 19 | ELF headers to determine where to transfer control. Unfortunately, |
| 20 | most older bootloaders -- APB or MILO -- hardcoded the kernel start |
| 21 | address rather than examining the ELF headers, and the result is a |
| 22 | hard lockup. |

| 24 | Say Y if you have a broken bootloader. Say N if you do not, or if |
| 25 | you wish to run on Wildfire, Titan, or Marvel. |

| 36 | This option is required for IEEE compliant floating point arithmetic |
| 37 | on the Alpha. The only time you would ever not say Y is to say M in |
| 38 | order to debug the code. Say Y unless you know what you are doing. |
