I have a little bit of knowledge about PC components but this is from late 90's and early 00's so excuse me if I seem a little n00bish. (I know my IDE's but not too hot on my SATA's)
I have a Gigabyte GA-73PVM-S2H MOBO and have a HD and CD-R setup on the only available IDE port on the MOBO.
I'd like to use another one of my IDE HD's in this system for a dual boot. (One for browsing, the other for working offline on my music).
Due to the lack of IDE connections I bought an IDE>SATA converter and have connected and plugged the second HD in. When I boot up, the system can see everything except the new SATA connection. I have tried the settings in BIOS, IDE, RAID and ACHI. (When I set up ACHI in BIOS, Windows saw a new PCI device and I installed drivers, but isn't available in 'My Computer' or as a bootable HD in BIOS.)
If I've missed any info, let me know and I'll post it up.
