I recently purchased the NetBSD CD from InfoMagic, fully understanding that
NetBSD might not run on my Macintosh Performa 550. I had seen vague
references on the internet to NetBSD running on a 550, but it seemed like a
long shot. So, if you can lend any clues I would appreciate the help.
Mac Performa 550
5 MB RAM
162 MB internal Sony HD
121 MB external Micronet HD
On my internal HD, I created a 100MB A/UX root/usr partition, a 15 MB A/UX
swap partition, and the rest is a MacOS partition which contains a System
Folder and the NetBSD setup applications (Mkfs, Installer, Booter).
I am not running RamDoubler.
I ran Mkfs on the root/usr partition.
I ran the Installer and installed: Base11, NetBSD11, Etc11. I also created
I rebooted MacOS with extensions off, and with the external HD turned off.
I then ran the Booter, chose the correct SCSI ID#, and was pleased when the
booter ran through it's business, prompted me for the boot, and seemed to
make it partway through a NetBSD boot!
Here's where things seemed to go funky, where it dropped into the debugger...
[lots of stuff about bootstrapping, moving ROMBase, video address, etc]

real mem = 5242880
avail mem = 2543616

mrg: 'Mac Classic II Roms' rom glue, tracing off, debug off, silent traps
adb: bus subsystem
Got following HwCfgFlags: 0xec00,0x 773f, 0x1b404926,0x 0
mrg: setup egret:
unknown OS trap 0xa247, no trap address available
panic: mrg aline super ()
Stopped at _Debugger +0x6: unlk a6
And there it hung up tight. there is no sign of any "grey bars". Should I
just give up? When it says unknown OS trap, is this because I'm running
7.5.1 - maybe I should drop back to 7.5
Also, 32 bit has been turned on in control panel - it probably should be
Thanks for your time and consideration, and please forgive me for asking
questions that I'm sure have already been addressed in previous discussions.
