If you'd want to boot from it your only option probably is to get a SATA->SCSI bridge like the ACARD AEC-7730A and hook it up to the on-board 53C876, the latter will be a bottleneck though as it's just UW. It could be that Sun add-on cards like the 375-3191 which is U320 and supported by mpt(4) have their own FCode which would also allow to boot from an SSD connected via a SATA->SCSI bridge to it. If booting from the SSD isn't required you can just put in some SAS controller supported by mpt(4) and directly connect a SATA SSD to it. There are also some PC-world SATA controllers which work in sun4u machines (check the archive for at least a working Marvell one). Generally there also are SATA add-on controllers which rely on their BIOS to be executed even when not booting off of them, which isn't the case in a sun4u machine. Marius
