Hi Folks,
After following the discussions, I'd like to summarize what MY OPTION on
the current status of /sbin/grub is:
* /sbin/grub from [EMAIL PROTECTED]:/gd/gnu/anoncvsroot:
It works as a testbed for the GUI. I.e. you can add new stuff
(filesystem, commands, ...) and get the chance to debug it under
Linux. NOTHING MORE.
Especially:
install= ...
testload= ...
fail (reason below).
* Brians patch ("grub patch to fix stage 1.5 and add chainconfig="
from Sun, 9 May 1999 20:28:54 +0200) applied:
The subject line talks about "stage 1.5" fixes and "chainconfig"
extension, however, he fixed also the basic problems with the
`grub_read' calls in "shared_src/cmdline.c:enter_cmdline "install") and
`biosdisk' in grub/asmstub.c.
While Brian did a good job, it's far from complete:

Only brave souls can use it to write to their harddisks yet IMHO.
However:
install= (fd0)/boot/stage1 (fd0) (fd0)/boot/stage2 0x8000 p
made a perfectly booting floppy for me.
* The bugs (at least what I found, no time to fix yet :-() are in two
directions:
a) ALL `grub_read' calls have to be checked, if they need RAW_ADDR
and if the memory behind is big enough ("testload" in cmdline.c).
b) The `open' check result sequences in asmstub.c:get_diskinfo need
rework
1) See Gords comment
2) open -> -1 on error!, the checks and logic assumes 0 (grrrr...).
3) Linux has some magic with respect to /dev/fd1, i.e. opens for
all devices hang some time when reaching /dev/fd1 (should be
handled).
Any fixes or ideas yet Brian?
That's it.
cheers

BTW:
People in charge of the grub rep should say which tools and versions
are needed and where to find them (currently `automake 1.4a' and
`makeinfo ?' make trouble).
