Firmware update R211 released for SanDisk Extreme SSD

I want to make sure I understand this before doing something I will regret. It’s my understanding that the R211 firmware update is for non-Mac machines and the R2111m is for Macs, right?

I have my Extreme 240GB SSD installed in a machine I built myself. The motherboard is an MSI X58 Pro-E. The South Bridge is an Intel ICH10R chipset. It triple boots between Windows 8 (Release Preview), Windows 7, and Ubuntu Linux.
