-One possibility has to do with the way the that the SCSI IDs are assigned. |
| 123 |
-Gentoo/SPARC developer Keith Wesolowski provides us with the following: |
| 124 |
-</p> |
| 125 |
- |
| 126 |
-<p> |
| 127 |
-Linux, normally, orders devices by SCSI ID. The lowest-numbered disk is |
| 128 |
-<c>sda</c>, the next-lowest is <c>sdb</c>, and so on. Note that <c>devfs</c> |
| 129 |
-allows you to specify devices by SCSI ID, so that adding a new device doesn't |
| 130 |
-cause your existing devices to be renamed, unless of course you use the |
| 131 |
-compatibility names. There are additional ways to solve this. |
| 132 |
-</p> |
| 133 |
- |
| 134 |
-<p> |
| 135 |
-The OBP in most or all sun4c and sun4m systems aliases "disk" to the device with |
| 136 |
-SCSI ID 3, and "disk0" through "disk3" to the device with the corresponding SCSI |
| 137 |
-ID, if it happens to be a disk rather than a tape, CDROM, etc. |
| 138 |
-</p> |
| 139 |
- |
| 140 |
-<p> |
| 141 |
-In the desktop systems of this era that support two SCA disks (the Aurora |
| 142 |
-chassis systems), the lower slot is assigned SCSI ID 3, and the upper slot is |
| 143 |
-assigned SCSI ID 1. |
| 144 |
-</p> |
| 145 |
- |
| 146 |
-<p> |
| 147 |
-If you like, you can change the PROM alias "disk" to match that of "disk1" so |
| 148 |
-that the <c>boot disk</c> command causes the system to boot from the same |
| 149 |
-device Linux calls <c>sda</c>. This feels more consistent and normal, |
| 150 |
-especially for users with a PC background. Alternatively, you can simply place |
| 151 |
-the filesystem containing <path>/boot</path> (which could be the root |
| 152 |
-filesystem or a separate boot filesystem) on device ID 3 (Linux <c>sdb</c>) and |
| 153 |
-boot from it, using a root filesystem on either <c>sda</c> or <c>sdb</c>, or in |
| 154 |
-fact any other disk attached to the system. |

-32-bit SPARC systems vary. Systems with the sun4m architecture have been |
| 174 |
-reported to work fine (SS4-SS20) including SMP configurations with the later |
| 175 |
-2.4 series kernels. sun4m systems using HyperSPARC or Ross processors in a SMP |
| 176 |
-configuration will have a lot of kernel related trouble. Additionally the |
| 177 |
-author hasn't heard of any user reports in regards to the JavaStations so its |
| 178 |
-status is unknown. sun4d based systems currently do not work in the 2.4 kernel |

-<p> |

-Often, the problems encountered in trying to run Gentoo on a 32-bit SPARC |
| 184 |
-system stem from the kernel. Rob Radez (not related to Gentoo) maintains a |
| 185 |
-webpage <uri>http://osinvestor.com/sparc/</uri> with the status of SPARC system |

-support for various versions of the Linux kernel. This can help indicate how |
