Dear NetBSD/i386,

My Iomega Zip100 drive worked just fine under NetBSD.  I recently upgraded
to an Iomega Zip 250 drive and I can't get it to work.  It is recognized
under NetBSD V1.4.1, but, I can't mount either a 100MB or a 250MB disk.  I
suspect that this may be a driver problem.  I get the following dmesg output:
