I'm upgrading my Father-in-laws old IBM Intellistation Pro M 6230.
After getting the SCSI drive MBR error fixed and reloaded the drive with a fresh copy of XP I started to upgrade the memory from 3 GB to 4GB.
I believe I got the exact same type of memory as the kind installed, but when I removed the two 512 MB RAM and replaced them with the 2 one GB sticks the system gave a beep code, (1?) but still booted.
I saw that it did not recognize the new memory. The system showed only 2GB of memory. I took out the memory and reseated it. Now it will not boot at all and I got a 3-3-3 beep code. The IBM documentation says that this means "No optional memory in the system"
I then tried various configurations of memory (making sure to use matched pairs for DIMM slots 1 and 3 and 2 and 4 as they suggest). I even went back to the same configuration with the old memory. It will still not go into POST and there is no signal to the monitor.
On the motherboard there are two red LEDs that are next to the DIMM which the documentation says means it is a DIMM error.
There is also a red LED on the mother board that says system error LED.
Now just to complicate this, I was also adding a SCSI drive at the same time. When the system booted the first time (with 2GB and not 4GB) the drive was recognized but with no drive letter. That was something that I need to figure out too. I thought that might have contributed to the problem so I disconnected it.
I'm fairly technical, and I've been through the manual and searched online, I couldn't find out how to get out of this pickle.
If you have any other questions to help with figuring this out I'll answer them.
