PS THe drive works via Serillel!
Had ot disable the SATA RAID ROM in the Abit's BIOS (didn't even realise the screen I'd seen for the last few months was in fact a RADI screen! I thought it only showed detected SATA drives...). Anyway, it seems all fine.
Indeed, already found it gives me more meaningful feedback on DVD-RW discs! They needed to be finalized and it indeed told me that (as opposed to the MSI "reads DVD- media" that returned, and I quote "shrug"!).
It's accessing drives and all fine.
I'm going to install the Ahead NEro Sutie that came with it and see if I can jump straight into coaster/DVD making!
PS It has a B firmware; bearing in mind it came sans screws, cabling etc and only the install disc I'm pleasantly surprised! It's the S9 variety.
