I have been absent for quite awhile due to a busy workload with school, just wanted to say that I think its great you're still working on this and have a bootloader work, also I noticed a few post later that you have some initial CD-ROM support working.
I have a couple weeks free from study atm so please let me know if you need any testing to be done on an SE/30 as I'll be happy to do so
Hey there! I feel you, I've also been pretty busy with work/life and haven't been on here much, sorry about the delay in responding.
As of now, if you want to try out the devel branch and see if things work on your SE/30 that would be awesome. I'm ready to call what's currently on that branch done as long as it works on those systems. If you do run into grief, let us know.
