I finally made some more tests, with netinst 20041024 (http://cdimage.debian.org/pub/cdimage-testing/daily/sparc/20041024/sarge-sparc-netinst.iso)
Power up, boot into solaris. Ran 'memconf' to discover the memory layout. This showed: U701, U601, U703, U603 had 64Mb DIMMs installed U702, U602, U704, U604 were empty # reboot Stop-A during "Initializing memory" step insert cdrom ok boot cdrom Initializing memory / SILO 1.4.8 Fast Data Access MMU miss ok reset Stop-A during "boot: disk" step ok boot cdrom Fast Data Access MMU miss (NB, no SILO banner) power down power up Stop-A during "boot: disk" step ok boot cdrom Fast Data Access MMU miss (no SILO banner) ok boot cdrom Fast Data Access MMU miss (no SILO banner) ok reset Stop-A _between_ "initializing memory" and "boot: disk" steps SILO 1.4.8 Fast Data Access MMU miss A note on the 32/64 question. The sparc chip in these boxes is indeed 64-bit. However apparently there were some errors in the chip design that forced Sun to make Solaris run in 32-bit mode. Maybe linux does not have this problem? Or maybe there is a PROM setting that needs tweaking, to force 64-bit? Hope this is of some use. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
