Actually this didn't work either but I tried this and driver2 attaches: - ld -dy -Bdirect driver1 -r driver2.o -o driver2
So the driver now doesn't crib for scsi symbols or the ones that driver1 is exporting.

I think you want ld -dy -N drv/somedriver -N misc/scsi -r driver2.o driver2 (Note that drv/somedriver would need to be installed in /kernel/drv/amd64/ -- assuming you had an amd64 machine. On SPARC it would be /kernel/drv/sparcv9/ and on 32-bit x86 just /kernel/drv/) The misc/scsi module is found in /kernel/misc/{sparcv9,amd64,}/scsi It should be present. Of course, if you're not using misc/scsi (i.e. the SCSA framework), then you can drop the reference to above it! - Garrett > In spite of this I'm getting errors after loading the driver.
