Hi again. Well, I tried much stuff including compiling David Howells PnP code into a 2.0.27 kernel. In the end, it looks like what solves the problem is a proper warm boot with loadlin. I used stripped config.sys and autoexec.bat files so that no drivers are loaded when linux boots. As a result, the PnP settings on the Logitech serial card are seen by the BIOS before the kernel loads. Then, /dev/cua3 is properly recognized and set to irq 10 (which is the Windoze setting I'm using).
I believe that a similar method will work for linux without the need for booting a M$ OS: Boot linux and then use Peter Fox's isapnptools package to set the board up correctly prior to a warm reboot. Assuming that one doesn't reboot several times a day/week, this should be acceptable. As far as I know, PnP support is far from ready for general distribution and incorporation into the linux kernel, but there are some workarounds available. Cheers. Syrus. ---------------------------------------------------------- Syrus Nemat-Nasser <[EMAIL PROTECTED]> UCSD Physics Dept.
