227On SGI systems, there are two bootloaders available: <c>arcboot</c> and
228<c>arcload</c>. Currently, only the Indy, Indigo2 (R4k variety), Challenge S
229and O2 are capable of using <c>arcboot</c> as a bootloader, whereas
230<c>arcload</c> runs on all the Linux-supported SGI machines. Unlike
231<c>arcboot</c> however, <c>arcload</c> cannot presently read EXT2/3 partitions,
232and thus, loads its kernels from the volume header.
