zfs discuss - Jun 2007 - ZFS on 32-bit...

I''m looking at replacing my current old version of Linux with 
OpenSolaris. The catch is that I''m running my home fileserver on a dual
P3 Xeon system, which is 32-bit.   Given that I''m not really too
worried
about performance, and that I don''t expect to be putting more than 6 
drives and about 2TB of space in the system, what (if any) kind of 
issues does ZFS have with running in only 32-bit mode?  I remember some 
discussions about limitations on certain buffer/structure sizes, but my 
memory is foggy, so...

with less then 2G ram, no worry... with more then 3G ram
and you don''t need mem in userspace, give it to the kernel
in virtual memory for zfs cache by moving the kernelbase...
eeprom kernelbase=0x80000000
or for only 1G userland:
eeprom kernelbase=0x50000000

How does eeprom(1M) work on the Xeon that the OP said he has?

its faked via /boot/solaris/bootenv.rc
built into /platform/i86pc/$ISADIR/boot_archive
