(SAS2IRCU also used to be similarly hard to find, but they've fortunately stopped that.) I've just got my own FreeDOS image with sas2flsh, megarec for DOS, and megacli, and it works perfectly fine with those instructions. If it makes you itchy, cut your own FreeDOS image and lob those binaries from LSI's site and $OTHER_SOURCE for megarec and then go to town. (You don't need megarec for crossflashing between IR/IT on an HBA, though, that's solely for when you're convincing an "actual" RAID card that it's just a dumb HBA.) - Rich On Mon, Aug 22, 2016 at 8:52 PM, Warren Block wrote: > On Mon, 22 Aug 2016, Karl Denninger wrote: > > I have a number of the Intel 6-port expanders in production servers and >> have never have had any trouble with them; they just plain work.
