Yes, I can test. Maybe also the miniroot.fs is meaningful and 
easier/quicker to test?

Right now I have a 6.1 system with retro-patched boot sectors I 
concocted years ago.

I tried miniroot today (slap on swap partition, I would also have an 
external hard disk available).

SPARCstation IPC, No Keyboard

Booting netbsd
Memory error during DMA transfer.
DMA control register = 3844d000 , DMA address = ffe83004
Extra scsi data. Fatal error.Data Access Exception
Type  help  for more information

is this the same error, just with a little more information? or is it 
something different?


Until I have a booting system, it is easier to test. Also, apparently my 
original CD-ROM caddy is aging too.. it just almost always ejects the 
CD... wonder...
It also needs real CDs and not CD-ROMs :)
To test the CD, I had to borrow another SCSI cd-rom :) Luckily I still 
have my d2 burner from Mac 68k times :)
