Dell just put BIOS A10 on their support site. (Check here)
They seem to have some issues with the server at the moment, the download link on the site doesn't work, so here's a direct link for you guys
BIOS A10 M17x R3
UPDATE: This is no longer available on the official Dell site, so I removed the dlownload link, I don't know the reason for this, but I assume they have to fix something. Probably they will come up with another version soon.
And as the past has shown, there are probably quite some other fixes in there as well. No word about the "SATA issue", only way to find out is to test it Please report back if you update, I'm curious about the results.
Will unlock the hidden menus as soon as I find time, as long as there's some interest.
