In any case doesn't that need a vFlash card not a standard SD/SDHC card? From Wikipedia: https://en.wikipedia.org/wiki/Dell_DRAC To take advantage of storage greater than 256 MB on the iDRAC6 enterprise, Dell requires that a vFlash SD card be procured through Dell channels. As of December 2011, Dell vFlash SD cards differ from consumer SD cards by being over-provisioned by 100% for increased write endurance and performance.[21] While there are no other known functional differences between a Dell-branded vFlash SD card and a class 2 or greater SDHC card, the use of non-Dell media prevents the use of extended capacities and functions.

P. -------------------------------------------------------------------- Pete, Thanks for your help!!!! I am beginning to be persuaded you are right. However, I have seen some posts about putting vmware either on the SD card or internal usb stick that made me think the SD card could be addressable. If Dell has this limited to Dell flash cards instead of a regular SD card that might explain some of what I am seeing. Greg

From Wikipedia: > >I think the SD card on the back of the IDRAC7 systems on the Dell 730xd are similar to this. They are accessible by the IDrac and dell software and are primarily there for emergency install of the hardware from known good media. I believe that vmware has a module which talks to the card so you can install software in vm's from said known good media. -- Stephen J Smoogen.
