I worked next to the same no its not. Apple's NewWorld OF is complete enough to have the full set of silo's features, and there is little reason for a code fork. silo now has much cleaner filesystem support making it much easier to drop new filesystems in (without breaking ext2 ahem). as well as nice things like transparent gzip support, a working message= variable, built in ls, and cat commands, tab key completion, etc. when looking to port these to yaboot i have come to the conclusion that it would be far simpler to add powerpc support to silo proper then to spend ages decrufting (read rewriting) yaboot. basing yaboot on quik was a good way to get us a quick and dirty working bootloader, but its not a good thing long term. > guys that did Sun's OF; they were hired to do > PowerHouse/FirePower/StarMax's OF implementation, so I suppose that > some ppc machines have better boot roms than others. i thought the clones just got thier rom from apple? -- Ethan Benson http://www.alaska.net/~erbenson/
