Like I said - hard to say.
Keep in mind he said that there was no AHCI option

- That could mean: "there is no AHCI capability on this system"
- or: "AHCI is automatic in RAID mode and there is no option to change it"
I can't help with the SSD question. I have not played with one yet
But I suggest starting a new thread and ask the question directly: "Will a SSD run properly in legacy IDE mode?" Someone here will know.
