This seems like the error which happens when there is no /dev/hd? special device, in which case the minix demo will make a normal file on the root-device, filling it up totally. Thus the "no space on root device". What does "ls -l /dev/hd*" give you under demo-minix? Are all the listed files block devices? I haven't used the minix demo for a long time - could it be that it doesn't support hd5-9? I guess I'll have to make a mkfs for linux in the near future, and make a new root-image with it, so ...

Urgh. This is definitely the kind of error I wanted least to show up. The floppy driver is the least mature part of the system, and any errors are likely to show up there. I'm unable to reproduce this error: the only way this kind of write error could occur is if the floppy driver is totally unable to read the first block. Normally write errors won't be noticed by the writing process: it just writes to the cache. This definitely looks like a driver bug: UNLESS you are using floppies that are...

G'day, I had the same problem but was more serious, after the message "child 2 died with code 0000", NOTHING happens. After I have copied everything from the "floppy root file system" to the "hard disk root file system", I FORGOT to do a sync. Syncing is VERY important, Linux uses a 1.5 Meg buffer, there will be alot of information lost if a sync is not done. Listen to the disk activity when you do a sync! I even did a umount /dev/hd2 before I reset the machine. The bootimage with 0x302 writte...
