Hum, I was just told that NetBSD does not support more than 16 meg of RAM
with a SCSI controller, is this true with ANY version of NetBSD? (1.0 or
whatever). If this is the case I need to know, cause I would be wasting my
time installing it on a scsi since I require alot more than 16 meg of ram :)
NetBSD doesn't support more than 16MB of RAM with an *ISA*-bus SCSI
controller. It works fine with EISA, VLB, and PCI controllers, with
any amount of memory. EISA, VLB and PCI aren't limited on address
lines the way ISA is.
Bounce buffer support won't make it into NetBSD until the version
after 1.0. If possible, I'd strongly suggest using one of the three
mentioned busses for your SCSI, just for the sheer speed advantage
alone, not to mention bigger memory support.
I believe FreeBSD 1.5.1.1 has bounce buffer support for ISA SCSI with
more than 16MB of RAM, however, if you need to use that 1542 with more
than 16MB of RAM.
