Hi guys

I have a 1995 IBM 360CE laptop. It works well, except for the battery which does not hold charge at all. Anyway, I want to replace the original HDD (340MB, currently working with no issues) with a 500MB CF card. I already got the adapter and the CF card, tested them in another PC, they work well. The problem is, that the laptop will not boot when I replace the HDD with the adapter+CF card combo. Checking with more detail, I see the HDD is a regular one inside some type of "caddy" which connects not only the usual 44 pins of the HDD but also the additional 4 jumpers on the far right (see pic). from my googling (https://stason.org/TULARC/pc/hard-drives-hdd/ … -ATA2-FAST.html), these pins are used to determine the master/slave/cable select settings of the drive, however since the CF adapter does not have these pins, I guess that's why the laptop fails to boot with it. I am attaching some pics of the PC, the original HDD inside the caddy and the way the adapter connects to the caddy (missing the above-mentioned pins). Any idea what should I connect there to make the drive recognized by the laptop?

Thanks and sorry about the huge post.
