Oooerr - not sure, I just installed/ran it all in/from / (ram space) with no HDD's mounted (frugal boot not full installed). I created a /DV directory and dropped the DEVX sfs into that and sfs_loaded with no copy. Downloaded your tar file to / and also extracted it to there.You are running in ram? Where was the kernel kit extracted to??
The space available icon in my tray indicates 148GB - so enough space there as being a frugal boot that indicates ram space not disk space.
I did swap out the slacko 5.3.3 kernel 3.01 for a 3.10 one as the former was non-PAE whilst the latter is PAE
50Mbit internet connect speed so usually there's no problems with downloading larger files, often I run puppy from the cloud (download a 500MB 'office' sfs from my google drive that supplements a PXE booted 100MB basic/core puppy).
I guess I should do a full install of FatDog or 64 Lighthouse and test using that as that's the more formal/usual/correct way as I understand it.
