The message you saw was normal, but still didnt resolve the issue. you can also try booting the system normally, but during the bootup process,  you should be prompted to press Cntrl E, once are in the menu, go down to the option that says Reset to Default. (note: this will cause the idrac to be returned back to factory settings)  Oh and speaking of factory settings, you can go into the bios screen, then press Alt F to reset the bios to factory settings as well to see if that clears  your message. 
Hello, Recently purchased two identical R900s currently running bios 1.2.0. Problem is one of them, when it boots up and you see the Dell logo and does the memtest, right after that the screen goes black for a quick second and you know how on the top right you have:F2 for setupF10 For boot optionsF11 For something I cant rememberF12 for PXEWhen its done with the Dell logo and flashes to where you'd see the Perc6 starting up and DRAC and all those goodies, it shows:F2 for setupF10 for bootF11 for somethingEntering PXE BootI have in the bios disabled via integrated devices PXE for all 4 network ports. They are set to "enabled" - Not "Enabled with PXE"Under boot sequence, it shows:Virtual FloppyVIrtual CDVirtual USBCD RomHard DriveDoesn't show the network card.Problem is it magically hits F12 every time it reboots, even when there is no keyboard attached. I cannot figure this out at all, does anyone have any ideas?
