I run Freebsd on several systems (nothing short of excellent). The ones in question are running 3.0. I have recently purchased a 20G Seagate IDE tape drive that I would like to be able to use with a Freebsd system. The kernel appears to have support for some IDE tape drives but this one does not work. My questions are 1.) does the IDE tape support work on smaller drives? 2.) If so, is anyone working on the newer, larger drives? 3.) If not, or they need assistance I would be willing to help with this development (I have a strong Unix background including kernel device drivers and 20 years of software development experience). My second question regards an error message from the kernel. The message is sio0: silo overflow which seems to indicate received characters overflow on the 16650. This is coming from the serial port on the motherboard of Dell 350Mhz system. Has anyone else experienced this problem? I suspect it has to do with interrrupt configuration on the motherboard resulting in missed interrupts, I also tried to putting in an ISA serial card and had the same problem but not as severe. I've tried both irq3 and irq4 and made sure that these interrupts were reserved for ISA devices and that nothing else was on that interrupt. I have successfully used the sio driver on other systems without this error. Thanks for any suggestions you can send my way (I checked the handbook and FAQ's first but didn't find anything relevant).
