install drivers and reattach that device?

You could try swapping the IDE devices around, for example put the PX-712A as Primary Slave and the LS120 and ZIP on the Secondary. Maybe the WD and the LS120 don't want to play nice together.

What is the reason for building dual cpu retro pc? I found a motherboard recently that has dual pentium 2 450Mhz cpus and I remember thinking that whats the point of having dual cpu pc like that because if you want faster, you might as well use P3 instead.

The love for the hardware, I suppose. 🤣 😎

this! 😁

i guess the LS120 drive might work when connected to another drive than the primary hard disk but at the moment I don't really have an option because that case is kind of messed up.
parts missing and so on so I had to mount the 5,25" drives using hot glue + carton 🤣
everything is mounted very well now (CD drive + ZIP in 5,25" bays and LS120 + hard drive in 3,5" bays but I can't really move anything 😁

I'll try another hard drive as soon as I get to the basement to grab one.

Nemail, may I ask, your PPros are the 1mb or 256k ones?

Hello,i used to have such a board.I sold it about a month aho.Anyway first thing to do is to change the onboard dallas rtc system.Believe me they give errors when not working correctly.Also try to instal the native smp os of that era.Windows NT it is.The board rocks big time!Also dont forget to install either a scsi or a sata bootable pci card.Onboard 440fx slows downna lot.And memory.You should instal 8 *64 mb .you can find them for below 5$ per module these days.
