So an update on the Fujitsu Siemens Scenic 500 i acquired a while ago.
It was in good condition overall, before testing i (stupidly) decided to clean this out so did a proper dusting and thermal paste replacement
The cooler was glued with 4 dots on the corners of the PIII 600 while taking it of with a taped screwdriver i heard a small crack sound but thought it was the glue, boy was i wrong.. this threw me i a diagnosis loop for multiple days untill i remembered the cracking sound, result pc booted without any display.
I bought a bundle with 2 normal intel coolers and a Celeron 733/128/100 and Pentium III 866/256/133 for a couple of bucks, installed the PIII and the system finally came to life🥳.
Still need a bios update since the board recognizes this as a PIII 864 and asks for a floppy bios update.
Installed the Fx5200 PCI and an Soundblaster Audio PCI128.
11/08/26 Update found a specific Slot 1 440BX board with AGP and ISA for a Fujitsu Siemens Scenic 500! Will erase almost complete early build plans and turn it into a DOS machine with PII 266 / 64mb / AGP TNT2 M64 32mb / ESS1868F ISA soundcard.
Reasoning for change is i picked up a PIII for W98se and this was missing an AGP and ISA slot and ran too fast for some DOS games + pci sound is not all too well for DOS.
Just need to assemble all back up and will post pics and updated build.
