- Greets!

- I just installed a fine BOCA 14.4K internal modem today,
- after much hassling with the interrupts and com ports.
- I finally managed to get no conflicts. Heck, after a while,
- I was even able to connect to other hosts.
-
- However, something strange (and unfortunately repeatable)
- popped up after I used the modem for a while. When I tried
- to heavily access the floppy drive, I got 'DMA overflow'
- and immediate program termination (the program was 'rawrite.exe',
- a program which writes an image directly on the disk).
- Rebooting, both hard and soft, didn't help one bit; I get a
- few tracks of the floppy rawritten, and then bam, DMA overflow.
- If I try again, the DMA overflow message is immediate.
-
- So my question is, what is 'DMA overflow', am I in trouble,
- and does it have anything to do with my modem? I am very loath
- to try to disconnect the modem, as it's buried extremely firmly
- in my computer's innards right now. I would normally just be
- looking ashen at such scary error messages, but the idea that this
- modem could have somehow done something bad to my pc makes my
- skin crawl.
-
- I'd love any answers or other helpful ideas at
- fortony@sonne.cso.uiuc.edu
- or
- rhodesia@wixer.cactus.org
-
- thanks much in advance. Don't be shy to write, I'm desperate. :)
