Hi,

First of all, English is not my home language, so if i type anything wrong, i´m sorry for that.

I bought a computer. It is an 286PC with a 12MHz processor.
When i got home with it, i created a boot floppy for MSDOS 6.22. It boots from the Floppy, and i can play some games with it from floppys.... So that part is functioning.

But the thing is, it has a Hard Drive in it. It is spinning up ,so the motor is good. But when i try to access C: or D: it gives that there is no C or D drive

When i start MSD from MSDOS 6.22, it only gives me the A: drive under Drives.
After that i tried to start Fdisk, maybe that that program can show me more info. But it also gave me the "No Harddrives found in this system"

When i start the PC, it first gives me a sceen from the Video BIOS, after that there is a one liner showing the RAM OK, KB OK and FDD OK. the rest of the screen is blank/black

What i know about the Hard drive is, it had a 34 and 20 pin Flat cable. And also the Molex connector for power and its a 5,25inch model.
About the Mainboard, i know its from Mitsubishi? It Shows "Mitsubishi Electric Corp¨. I tried to google for some numbers and the IBI.M4V0, but didnt give a good result.

Anyone who knows anything about this machine?

Can you enter the CMOS Setup?
You need to enter the HDD parameters into CMOS...

Nie tylko, jak widzicie, w tym trudność, że nie zdołacie wejść na moją górę, lecz i w tym, że ja do was cały zejść nie mogę, gdyż schodząc, gubię po drodze to, co miałem donieść.

Thanks for your help.
The next question would be, how to enter the BIOS? It does not show a message to enter the BIOS.
But after the Video BIOS, i tried different keys, all function F keys, del, insert, home, control, shift.

I heard from someone i need a "g-setup program" on floppy to enter BIOS, but i dont know anything about that.
