Get stage0 and stage5 working. Try to reformat this code to be a little more human. Weird europeans have been writing this, and can't even seem to agree a single coding style for more than 4 consecutive lines! :-) 1994-11-02 06:19:53 +00:00			`static unsigned char *welcome[] = {`

Add a chance to read the release notes, too. 1994-11-05 08:20:08 +00:00			`"2. Release Notes",`
Make ShowFile() now show gzip'd text files. This should save a fair bit of space on the install floppy. Modify stage0 and the target names accordingly. 1994-11-05 23:12:10 +00:00			`"Read the 2.0 Release Notes (recommended).",`

Stage0 can't dump you into a shell. There isn't one. Just reboot. Stage5 didn't have a large enough dialog box. Fix that. Also use Andrew's autosizing code. 1994-11-02 09:05:49 +00:00			`"Don't do anything, just reboot.",`

Fixed to make sysinstall work again. Notable changes: Removed a dialog_clear() which somebody aimlessly had slammed into TellEm() in absence of any understanding of the structure of this program. :-( Skip through stage0 for now. Make write_bootblocks write the disklabel using the kernel-call, and forget about the boot-blocks for now. This is wrong, but I havn't found the real problem yet. I will continue work on this problem. Added a Debug-feature. There is a printf' like Debug() now which sends its output to ttyv1 (Alt-F2), and all "discarded output" from sub-processes end up there too. Made TellEm() put it's messages there also, so that we can see where what happens. Set the PATH for the shell we shouldn't start at the end :-) set "npartitions" after the disklabel-editor returns, so that we actually can edit all the 8 parts of the label. 1994-10-29 10:01:40 +00:00			`void`

Added a (H)elp function to the fdisk/disklabel code, much needed, now I only have to write the text-file it will dump on you. Stopped using cleartoeol in AskEm(), just as a test to see if the screen looks more sane. Added a attempted auto-recognition of /, swap and /usr for the first disk where it looks sensible. Logic of this might need to be improved. Made a "ShowFile()" which will not bomb/ignore you if the file isn't there. 1994-11-05 03:34:22 +00:00			`ShowFile(README_FILE, "Read Me First");`
