Dell has issued a critical BIOS update for the Dell Inspiron 530 series. BIOS Update 1.0.12 adds new Intel processor support as well as updated Intel microcode.
But, much more importantly, it fixes a buggy memory map for systems with 4 GB of memory or more installed. Considering I have 4 GB of memory in my system, I was affected by this… but not greatly, as my 530 is using Vista 32-bit and only addresses the 4 GB during POST.
Anyways, 4 GB of RAM or not, all Inspiron 530 owners should head on over to Dell.com and get updated.
