As dkelly@hiwaay.net wrote: > This is really why I'm replying to this older thread: Selecting "Load > Defaults" in the BIOS setup cured my floppy problem. Tor Egge tracked it down to an apparently broken floppy chip (most likely, the chip doesn't report DMA overruns correctly), and submitted a workaround that enables the FIFO on chips where this seems to be applicable. This hides the error well enough, and is also a good explanation why other operating systems on the same hardware didn't experience problems. Try the most recent -current, and see how it comes out. If it doesn't break for anyone, this might be a 2.2.5 candidate as well. (I tried it on an actual NE765-compatible 40-pin chip, and it doesn't break there either.) Terry submitted me a larger patch that is supposed to classify a good deal of FDC chips by feature categories, but i have yet to find an hour silent enough to test this. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
