You have a number of quick and dirty alternatives. 1. Since you wish to only use 20MB for dos on a 80MB drive you can simply use the original tinybsd disk to install on the connor drive. Then edit the disklabel to make swap bigger provided that the bsd partition is the last one on the disk. You will have to make the "a" partition correspondingly smaller for example if install makes wd0a CYLS 900-1000 and wd0b CYLS 1001-1024 you can change it to wd0a CYLS 900-990 and wd0b CYLS 991-1024 and then you can install netbsd or freebsd over top of it. Then you can disklabel and newfs the seagate and mount it in your fstab file for additional space. Since you only have 5MB of ram the 5 meg swap created by the tinybsd install is technically big enough. 2. It is also possible to set up *BSD entirely on a second drive with the first drive being entirely dos. You attach your seagate as the primary drive and install a *BSD to the entire drive. You then install Julian's boot blocks if they don't already come with the *BSD. You then modify them to default to the second drive in boot.c by changing the line part=unit=0; to part=unit=8; (this is untested by me but should work). Then re-install the modified boot blocks and reconnect the drive as the second drive with the connor as the primary drive and install either BOOTEASY or os-bs on this drive (whichever allows booting from a second drive). You should then be in business..
