David's latest sysinst (http://mono.org/abs/sysinst6.fs.gz) appears to
run installboot properly. At least I get good output from it (I think
the same as I saw with a working NetBSD 1.6.1 install). I'm just not
sure yet if it really worked because I can't get to a bootable state yet.
But assuming it does, nice work!
The next step for me was to get booted up on the ATARITT kernel where I
have networking. From there I tried an install to see if the hard drive
boot will work. I'm happy to report that as of the 11/09 build, the
ATARITT kernel boots for me and I can get networking. But getting
further with the install has been difficult...
I made two attempts tonight to get 200811090002Z installed but in both
cases I hit different kernel panics. The first one died extracting the
first large set. I got:
[... panic details ...]
As Tuomo suggested, the panics may be fixed by trying a kernel
with ST_POOL_SIZE=24 - I've put one up at:
http://mono.org/abs/netbsd-24.gz
David, I think you had previously discussed some changes that would cut
down the size of the ATARITT kernel. Please do make that change, since
as of right now the ATARITT kernel is just slightly over the size of a
1.44MB floppy when gzip'd. I used ghostlink to transfer it, but it's a
bit awkward and slow.
The changes I made (already committed) dropped the size of
the ATARITT kernel by around 170K by removing 68040 support.
How are you copying the kernel across - putting the gzipped
file on a floppy then using TOS to copy it onto the harddisk
before booting it?
There are a few options to avoiding ghostlink, some would be:
a) Drop some devices or filesystem/protocol support
b) strip the kernel - this removes the symbol table and which is
used to provide the backtrace on a panic, but if you just
want to see if things work it can be helpful. If you are cross
compiling your NetBSD kernels from another box you should find
build.sh has left a strip binary as
tooldir.$(OS)/bin/m68k--netbsdelf-strip
And you can just run .../bin/m68k--netbsdelf-strip .../netbsd
I've put a stripped version of netbsd-24.gz as:
http://mono.org/abs/netbsd-24stripped.gz
It *should* work fine, but if you hit issues try the netbsd-24.gz
one above.
c) Use bzip2 (gunzip first if its gzipped). You'll need a bunzip2
binary or other tool which can extract bzip2 on the atari side,
but the above kernel which is 1440K gzipped is 1344K bzip2ed
d) Split the file up. 'split -b 1400k netbsd.gz' will split
netbsd.gz into multiple files named xaa, xab, etc. To
put them back together in NetBSD (or any other system
with a 'cat' command) just run:
cat xaa xab > netbsd.gz
e) Adopt the split floppy bootloader approach as used by
NetBSD/i386 and various other ports. This is similar to
NetBSD/atari's code to load the miniroot from multiple
floppies, except the bootloader knows how to load a
kernel from multiple floppies.
Longterm e) is probably the preferred option :)
Also, even thought we don't yet know for sure if boot works yet, your
installboot change at least allows me to get further with the install.
Can you submit it?
Could you test netbsd-24.gz or netbsd-24stripped.gz first? I'd
prefer to commit all the changes together and retire the old
miniroot / prepare code at the same time :)
Thanks
