DMA (maybe) and tape drive problem (PANIC)

[John Watson]

Additional info on my previous posting, 486 with OPTI chipset panics on
2 or more DMA access at same time...
The board has an 82C206 chip for DMA and other functions.  The Semens chip
does not work (tried 2 with identical results) and a chip by the same number
from Chips & Technologies does work.  It appears that my problem is gone.
There is a difference between these two chips and it is not just a "minor"
timing variation.  Netters beware.           John Watson
