I have this Siemens Nixdorf Pro c5 specs: Pentium 133Mhz, 64M ram, HDD 40Gb (for testing), the Model of the motherboard is D943. The hard drive does not show up properly in the bios, its a Seagate Barracuda 7200.7, model: ST340014A, I found a 3 Drive IDE cable and connected it properly, I have tried different configurations on it on different IDE connectors, In the bios I can go to Hard drive 1 and select Autotype and it fills all the values, eg heads, cylinders, but it only shows up as 8.45Gb, I have LBA enabled and other options too, I tried the cable in different positions aswell, the manual I got is from https://www.manualslib.com/manual/769193/Fujitsu-D943.html anyone got any ideas on how I can solve this problem?
