But there are plenty of DIMM types On 860 there are some choises: -there are a lot of jumpers (or 0-ohm reistors) -use only one type of DIMM(which is not acceptable) -use somechip selects,and there are MEMORY HOLES in them Q: Is there any simpleway to use non-linear addresedmemory in linux? If so, how to enable this in kernel? for example there is: 0x0000_0000 .. 0x001f.ffff memory 0x0010_0000 .. 0x002f.ffff NOTHING!!! 0x0020_0000 .. 0x003f.ffff memory -- * * * * * * * * * * * * * per pedes ad astra! * * * * * * * * * * * * * mailto:krom@dgt-lab.com.pl ** Sent via the linuxppc-embedded mail list.
