Looking for a little help with the 486 pc I've just built. It started out as an osborne 486 with a micronics board. The motherboard was dead and i replaced it with a board out of an ibm value point. It fits perfectly into the case, only part that doesn't work is the vlb riser card. Its a different pinout but i have one suitable for the ibm board on its way. I had the common 528mb hard drive limitation, its a 3gb Fujitsu that i partitioned as 528mb for the time being to get around the issue. Every time i turn the computer on it reports memory error and memory size error, going into the bios menu it reports the correct amount of memory installed. Once i enter the windows installation the first error i see is when loading DOS, i get a PCI READ CONFIGURATION FAILURE, after that things continue on as normal, i can format the drive and input the installation command. The installation begins and runs scandisk and passes. After this the installation hangs with the message "Not enough free extended/xms memory to run setup" I have no idea why the motherboard is rejecting the memory and it doesn't matter what order i install the sticks. I am unsure if it is the cause of the xms memory fault. I haven't touched hardware this old in 15 years and i was a little kid at the time so i'm not up to scratch.
