I have Chameleon booting OS X on a RAID 0 pair of X25-Ms, and storage and backup partitions on a RAID 1 pair of Seagate 1.5TBs;

With RC1 I get sixteen repeating sets of `EBIOS read error: Error 0x01' and `Block -1364952312 Sectors 64' lines before the Chameleon countdown timer. If I then press a key during the countdown timer I get eight sets of `EBIOS read error: Error 0x01' and `Block -1364952310 Sectors 64' lines, eight sets of `EBIOS read error: Error 0x01' and `Block -1364950248 Sectors 64' lines, and four sets of `EBIOS read error: Error 0x01' and `Block -13649550224 Sectors 64' lines before it freezes.
At least with RC1 it can boot, but with RC2 the Chameleon countdown timer never shows, and it goes through all thirty six sets of ebios error lines before it freezes.
This seems to be related to libsaio's sys.c inability to cope with the Seagate 1.5TB drive, and fdisk reports negative geometry as well;

There's a similar Solaris problem here;
