Nearly three years ago, I had an unsuccessful try to get MacBSD running
on my Macintosh Classic II. This was not a miracle, since the Classic II
was not supported then. I was very excited when some days ago I read
that the Classic II is supported by NetBSD/mac68k 1.2 now! (And even
before, but I hadn't been following the story closely.)
So I got the software and tried to get my Classic II boot NetBSD 1.2,
which didn't work. I'd appreciate any help.
Let me say in between that I have little knowledge of Macintosh
programming and Macintosh hardware details, but several years of
experience with several Un!x variants, including 4.3 BSD and FreeBSD.
The details:
(1) Hardware
Mac Classic II, 10 MB RAM, FPU;
ADB Mouse, ADB keyboard
(an older one, I think the first ADB keyboard Apple built);
700 MB internal disk Quantum Lightning 730 on SCSI ID 1, 2 HFS
partitions
(~50 MB for System, the rest for Applications etc.);
170 MB external disk Fujitsu M2614SA on SCSI ID 5, 2 A/UX partitions
(~32 MB A/UX swap partition, the rest A/UX root).
(2) System Software
On internal disk:
- 1st partition: HFS, System folder MacOS 7.5.5 with some extensions
- 2nd partition: HFS, mounted from 1st partition
On external disk:
- 1st partition: A/UX swap
- 2nd partition: A/UX root (NetBSD/mac68k 1.2; installed as proposed
in the Installation notes -- I know these are from 1.1, but apparently
there shouldn't be much of a difference.)
(3) Installation
I installed NetBSD/mac68k as proposed in the Installation Notes:
- partition the disk (see above, SCSI ID 5)
- mkfs on sd1a
- build devices
- install base12, comp12, etc12, games12, man12, misc12, netbsd12,
text12
Everything went fine so far.
(4) Boot Setup
The options in the booter program are set as follows:
- Preferences:
- Autoboot on Startup: no
- Debug level: 1 (tried others as well)
- Log to file: [yes, see below]
- Boot Options:
- Single user: no
- Extra debugging info: yes
- GMT bias: 0
- No env dumps: no
- Don't disable VBL interrupts on video cards: no
- Don't bug me about untested machine: yes
- Show dialog and wait before booting: no
- Halt boot on non-fatal errors: yes
- Kernel location: NetBSD/mac (sure, I'm brave)
- Kernel name: netbsd
- partition name: sd1a
- Root SCSI ID: 5 (the external disk, see above); Ask?: no
- RAM (#MB): 10
- Auto-size RAM: yes
(5) Booting
When I boot this configuration, the bootlog seems ok (appended below).
After that, the screen goes white and the following appears:
-------------------------------------------------------------------
[ preserving 93836 bytes of netbsd symbol table ]
Bootstrapping NetBSD/mac68k.
Getting mapping from MMU.
System RAM: 10452992 bytes in 2552 pages.
Low = 0x0, high = 0x9f8000
no internal video at address 0 -- videoaddr is 0xfee09a80.
Done.
Bootstrapping the pmap system.
Pmap bootstrapped.
Moving ROM base from 0x40a00000 to 0x9f9000.
Video address 0xfee09a80 -> 0xbf9a80.
-------------------------------------------------------------------
[Inaccuracies due to my typing.]
Then the machine hangs. I'd be glad if anyone could give me some hints
what I could try to make it work.
And, by the way: You folks have done a great thing porting NetBSD to the
Mac! Thanks a lot!
