+1 I also would like to hear about that. Maybe even some more general information how to do this right. If I would buy a (used) case like that today, it is usually already missing some 5.25 drive bay covers. Just fitting in a generic beige CD Drive is certainly not the solution. How do you get a …

No luck unfortunately with my attempt to fix the board. I cleaned everything and retinned traces as good as possible and also added a few new wires (+ the new replacement resistors). Continuity was ok on all damaged traces but the board is not waking up. CPU, chips and VGA chip are getting warm …

Hi everyone, I am currently looking at a 386 board that has a pretty severe Varta damage. To clean off and restore tracec I have removed the keyboard connector and some of the resistors: 20240513_141335-2.jpg 2 resistors got damaged while I tried to remove them (the diode seems to be still ok ?!). I …

Yes, Im using partitions 2GB or less in Dos 6.22. Also what I think are good quality ("industrial") branded cards. But why would I get such an eratic behaviour? The Motherboard, the XTIDE card or the CF card? What is the most likely source of the problem (remind you a small 128MB card works without …

Im also wondering, to access larger than 504 MB partitions, the bios needs to allow LBA addressing. So is there some configuration of the XTIDE bios required to allow/enable that?

Yes, I have a few small CF cards, but none of the available options fit any of the geometries. On the other hand the XtIDE worked out if the box, but only with small cards.

Ok - Im now confronted with a new set of problems. My HDD solution for the machine is a monotech XTIDE card. (XT-IDE Deluxe) So far this card has worked flawlessly at an 8Bit ISA slot with an (older) very small 128MB CF Card. However, my actual idea is to eventually use a biger drive. However all …

The speaker works ! JP13 is indeed a second (?) reset switch and works too. The rest, unfortunately - seems not working. None of the LED's lights up and none possible combinations is slowing or accelerating the system. Not sure why this is not working Thanks for the suggestions

Ok - Im getting very close - but I got yet another question. As mentioned before there is no documentation available for this board. My case has a Turbo switch, turbo LED, Power (?) LED, Keylock and a reset button and - most importantly - a good PC speaker. Reset is the only labeled header on the …

Hi again, tried the Checkit software. I dont have a loopback plug but it is still testing the com1 port and all tests are passed. Ct mouse also comes with some test utilities. They all see a mouse at com 1 (IRQ4) at 3F8H. They also see for example if IRQs are wronly jumpered (i.e. if multiple …

Ok - big step forward. I found the same card with good pictures on ebay and simply copied the jumper config. Now FDD and HDD interface work. The only thing thats not enabled is the mouse port. Hach - cant have everything...
