Ok, I worked on this for awhile last night and made more problem, no solution.
Summary of current situation, which I may just have to live with at this point,
Reboot to dos no longer works, instead of rebooting to dos, system reboots. (Win98 SE)
Onboard sound and speaker are now both disabled, but if you listen very carefully, close to mobo speaker, at the time the network prompt shows up on the screen, the speaker is still emitting the stacatto machine gun noise, but now there are also very infrequent intermittent short beeps interspersed with the clicking.
Speakers on desk are now plugged into a CT5807 sound card. After I respond to the network login when the Windows 98 desktop comes up, The sound announcing the arrival of the desktop has a couple of warbles in it.
After all the preliminary issues, the computer seems to play a cd ok.
-------------------
What I did:
First, in preparation for adding a sound card, I removed the sound cable to the cd from the motherboard. Only -- it wasn't the sound cable. It was the USB 2nd port cable(s) and it wasn't 1 connector, it was 9. I had no clue about that - I think I finally got that worked out after lots of reading in the manual and on connector ends. However; I did have a case ground hooked up to a cable ground for awhile in the process because the cable markings did not correspond to my manual markings and I did not understand there were 2 types of grounds - don't know if that made any additional problems in the motherboard.
Then back to my original project - I got an old CT5807 sound card and thought I would try replacing the on board sound with that. I tried various combinations of the CT5807 and the network card in PCI slots 1,2, and 3. None of them worked. Sisoft Sandra showed lots of useage of interrupt 11, but none on interrupt 5. I tried to reset the CT5807 interrupt to 5 in the device manager. That would not work - the creative software forces it to int 11. After getting no results with various combinations, I studied the manual for awhile and settled on the following configuration:
PCI 1 blank (leaves agp with no competition),
PCI 2 network (leaves network with no competion),
PCI 3 CT5807,
PCI 4 LPT 2 PCI printer card,
PCI 5 blank.
I then went to bios and set INT pin1 to pin4 assignment for PCI 3 to interrupt 5.
Rebooting, I have the results at the beginning of this post.
Rebooting again, I checked the bios, it does show 5 for PCI 3; however, when machine is fully started, Sisoft Sandra still shows no useage of interrupt 5 and the creative software continues to force the CT5807 to interrupt 11.
The floppy drive access light is not on when the machine is making the clicking noise when waiting for network login.
I do not have, and will not be provided, a substitute network card or memory for testing.
------------------
Like I said above, I suspect I may be at a point where I'll just have to live with the situation as it is.
Regards.
