Thank you feipoa and Imperious for all of your help, suggestions, and information. I found my multimeter, and I was able to determine where the wires belong, and now CTMOUSE is detecting my ps/2 optical mouse. Now I can move forward with the project as now everything seems to be in working order.

I have a multimeter somewhere, I will see if I can hunt it down. Looking at the manual, I am assuming that the mouse pin closest to the keyboard port is pin one. The thing is, I flipped the connector to make sure I didn't have it connected backwards, and the optical mouse lights up regardless of the …

As I mentioned earlier, the ps2 to serial adaptors only work with dual mode mice that usually have a switch to select between serial and ps2 operation. They will not work with more modern ps2 optical or ball mice. Sorry if this is a stupid question, but I assume You have turned on the ps2 mouse …

I am beginning to think that the ps2 mouse header on this board is dead, and I have no other options for testing.

No mice work with 2 different ps/2 to serial adapters. A serial track ball works. On my ps2 connector, I swapped the yellow and blue wires, and CTMOUSE still doesn't see a ps2 mouse.

I am going to mess with pins and wires soon. First, I am going to test with another mouse or two. This optical mouse lights up when I use the PS2 port, though without being detected by CTMOUSE. I just connected it to the COM1 serial port with an adapter. The mouse remains unlit until CTMOUSE loads, …

Thank you much, for your reply. I will look into the bios chip issue. Do you have any information on the mouse issue? I am still thinking that my connector's wire layout differs from the mouse pin layout. I have the one 5 pin, single row connector, and a 2-row connector which will not fit, but has a …

In addition to the mouse connector issue, I tried to flash the bios to 1.72. I followed the instructions, but I get an "erase chip fail" error and the bios will not flash. It is currently version 1.5. I cannot believe the string of issues i am having. All have been fixed except for the mouse and now …

I build computers of various sorts. I have three retro hobby computers I have been working on. The last 486 was perfect until the board died; it had PCI slots and PS2 ports for keyboard and mouse. Some of this is new, such as the CF-IDE adapter, etc. I uploaded a pic of the mouse connector. I was …

Of course, I have run into more issues. CTMouse doesn't detect the mouse (I have a ps2 bracket adapter connected to the mouse port on the motherboard.) Also, when I connect a cdrom to the secondary IDE port, it cancels out the Primary port. Argh...

Ok, so I swapped out the 486DX2 with another one. During boot, the board recognizes the CPU as 80486DX2-S at 66Mhz, rather than a P24D-S. It also successfully boots to my multi-config.sys, so I am diagnosing the problem as a CPU issue with the original CPU. Now to put a fan on the replacement CPU, …

I grabbed another RAM module and a couple 486 CPUs to test when I reset everything. I know that the CF-IDE is good, as it boots up in another machine. Do these boards have any issues with FAT32 drives? I have MS-DOS 7.10 on there, and the CF is formatted with FAT32. Though it is still strange to be …

I am not sure what is going on with this board. It will not boot from floppies, or the CF-IDE adapter. If I use a floppy emulator with a dos boot disk, or an actual floppy drive with a dos boot disk, I get "Starting MS-DOS," but it just hangs there; the system isn't locked up as I can hit capslock …

I will try that tomorrow. However, I am thinking I am either cursed or this board is having issues. Regardless of the floppy drive I am using, this board will not recognize or boot from a Win98 boot disk, or gives me an I/O error. When I try to boot from an MS-DOS 6.22 setup disk (two different …

Thank you for your reply. With External Cache disabled, I am able to get to the DISK BOOT FAILURE notification, so I am going to connect my drives and test further. I didn't have to disable external cache prior, so I am wondering if my CPU is now having issues.

After further experiments with the BIOS settings, the hanging occurs when the External Cache is enable. Could my CPU be on the fritz?

Greetings, I have a Zida Tomator Board 4DPS ver. 2.1 board which I was hoping to use for a custom hobby build. I tested the board while it was on a piece of cardboard, I successfully set the jumpers to recognize my 486DX2-66 CPU, and was able to use a CF adapter to transfer files. Everything seemed …

Thanks, all! So in order to avoid the noise, I will try CDBeQuiet and other experiments. It is difficult to keep a retro PC authentic as possible. I found very few quad speeds on ebay as of late. As parts fail, I will probably have to just use dosbox.
