There are two likely problems that you are encountering. One of them is the sorry state of the FreeBSD lpt driver (don't throw veggies at me folks, please :) Sometimes, it's just slow, as if it were missing interrupts. I don't know what it is, and cannot afford to try another kernel on my only BSD machine. Usually, the driver will get to behave better once the device has been closed, and then it keeps running okay. Usually... What I do to resolve this state is that I send a couple of printer resets at the machine power-up, hoping that there is nothing else queued for the printer. The other problem could be one of those PnP software configurable sound cards emulating Sound Blaster. I've had some different ones (all with UMC chipset) and they seem to occupy IRQ 7 at power-up, even though they are not fully initialized at that time. Either move your printer interrupt elsewhere (beware, the sound card might be occupying the IRQ 5 for the MPU-UART) or boot DOS first and configure the casrd elsewhere (followed with CTRL-ALT-DEL or, perhaps fbsdboot.) Good luck, /Alby > Thanks > Greg Shaffer > -------
