Hello! My hardware: http://www.supermicro.com/products/system/1U/5015/SYS-5015B-MT.cfm
The difference that memory is: 2GB RAM We've tried release 2009.06 as well as latest 121 build on CD and USB. Both of them are stops at the point while checking devices. That's clearly not CD/DVD drive problem and not 64/32 bit problem. We've added option "-B acpi-user-options=0x8" to GRUB etc. After some debug, we've managed to boot till some point 32bit kernel (pity though) and it still stops at ISA-device: pit_beep0 and then fun stops. We've also upgraded BIOS to 1.3 version. No changes so far. We also tried this: http://bugs.opensolaris.org/bugdatabase/view_bug.do;jsessionid=1cec20a2d726affffffffcfc5d3bc1fb21b6?bug_id=6819642 Still no luck. Anyone has some useful tips how to get rid of Linux Ubuntu Server and FreeBSD that, "unfortunately", works with zero problems? :-) Any debug options? Anything else we can try? Thanks for any help, if any... -- Kind regards, BM Things, that are stupid at the beginning, rarely ends up wisely.
