Looking for someone with an ASUS P4C800-Deluxe

[wpshooter]

As I described in another thread, I am getting this weird problem on my ASUS P4C800 Deluxe motherboard.

If I set the number of USB ports setting in the BIOS to any number less than 6, then the system will NOT boot to a WIN98 bootable diskette. If I set the number of USB ports to either 6 or 8. then the machine will boot to the WIN98 diskette just fine.

I have tried 2 different floppy drives and I get the same results as described above. I have also made a new fresh WIN98 bootable diskette, which other computers boot to just fine.

I have reloaded the default BIOS settings and then tried the above described settings for the USB ports and I get the same results.

I have also, reset the CMOS by alternating the jumper setting on the motherboard as described in the M/B owners manual and again I get exact the same results as above.

HOWEVER, strangely, I also have an ASUS P4C800-E Deluxe motherboard and I can set the number of USB ports in the BIOS to anything from 2 to 8 ports and the computer will boot to the WIN98 floppy just fine, go figure !!!

If anyone has an oldish ASUS P4C800 Deluxe motherboard would you run this scenario and see if you have this same problem booting to a WIN98 floppy when the BIOS parameter for the number of USB ports is set to less than 6 ?

Thanks.

I have a P4P800 Deluxe I865 chipset board that doesn't have this issue, it was a close cousin of the P4C Deluxe

Thanks for the response.

Do you think this is a bug in the P4C800 Deluxe board ?

Is there "supposed to be - by design" some relationship between the USB port settings and the functioning (as in properly booting to) of a floppy drive ?

Thanks.

Bios support for USB devices was notoriously flaky on these boards, it wouldn't supprise me, I had to disable legacy USB support to overclock and keep PAT enabled 🙂

Thanks again.

I am about to start building myself another system and I sort of hate to say this, but I think on this system the motherboard is going to be INTEL and not ASUS or anything else. Might not get all of the bells & whistles but at least hopefully all of the functions will work as they are designed to.

Thanks.

I would just leave all 8 ports on It shouldn't effect your performance and even if you not using some of the usb headers it won't hurt to have them on, truthfully I'm not really sure why they ever had the option in the bios to shut off some of these ports seemed like a useless feature 🙂 The P4C Deluxe was one of the best skt 478 motherboards ever made It did have some quirks but if you still have one along w/ a similar era P4 I'd take it over just about any other stk 478 board.
