PowerEdge 2800 Boot Problems after resetting NVRAM_CLR jumper
Posted on 2011-02-25
I was getting an error on one of the rows of RAM so went about replacing it, but the machine wouldn't recognise it even though the vendor said the RAM was identical. I searched forums and found a tip to reset the NVRAM_CLR jumper in order to get the BIOS to recognise the RAM. I did as instructed, but it didn't work, so I just replaced the old row of RAM and set the jumper back to the default position. The BIOS recognised all the old RAM, including the one that was producing the errors.
Now a new problem - on reboot I got PXE-E61: Media test failure, check cable error. So I went about checking the cables, swapping some new ones in, reseating the drives etc. Nothing worked. Then I thought to look at the BIOS and the SCSI RAID controller was set to OFF. So I turned that back on and watched the starup sequence.
All the drives are being recognised. but now Windows (Server2003) doesn't start, I get to the very first spash screen for a second or two and then the machine restarts. Its stuck in a loop, I've tried every windows boot option, but nothing works.
I have 2x SCSI 320Gb drives mirrored.
Can someone please help me out of this loop?
