Ok can not do bios update via 2003 server ... needs to be xp/2000. Installed XP on the machine via RIS and was able to flash the bios and now all is cool !  
Hi, Does anyone have a copy of the flash bios utility for a power vault 725n system. I know this is an old machine, but Dell just dont seem to want to publish the files!   Regards, Malcolm
PC725N Bios Flash Utility?
