My friend recently purchased a 486/33DX from Micro Professionals and we have recently discovered a rather large problem with it. It seems that neither one of the floppy drives want to write or format. After numerous calls to their support line. We finally got a phone call back. Their solution was to reinstall DOS. What kind of fools do they consider the end user to be?
Regardless, we still need advice on what the problem is. It appears that the contoller card is to blame, but we can't be sure. Normally, from what I
understand, multi-io/IDE controllers have two seperate jumpers for read and write, but this one only has a jumper to disable floppy support and one to change the floppy address. Neither of these seemed to have helped.
In addition, another symptom of what we believe is the same problem arose. That is that any DMA access to channel one will lock the computer up to the
point that only a Hard reboot will even get it started again.
We are as of this moment considering writing a letter to Computer Shopper and the Better Business Bureau about this.
Any help regarding this would be greatly appreciated.
