Science Lines: 32 Distribution: world Message-ID: <32luinINNrkl@soccer.cis.ohio-state.edu> NNTP-Posting-Host: soccer.cis.ohio-state.edu I thought FreeBSD 1.1.5 was supposed to be able to handle greater than 16 megs of ram for any machine type, but when I boot only 16 out of my 24 megs are recognized. Is there something special that I need to do to get the other 8 working? Joel B Wood wood@cis.ohio-state.edu Note from the FAQ: ____________________________________________________________________ 1.5: I have 32MB of memory, should I expect any special problems? If you have an IDE controller, no. Likewise, if you have a full EISA system with EISA disk controller or a working local bus controller (read further) you'll have no problems. If you have an ISA system, or an EISA system with an ISA disk controller then you will most certainly have problems with the upper 16MB of memory due to the ISA 24 bit DMA limitation (which ISA cards in EISA systems will also exhibit). If you have a local bus disk controller, then you should be OK, UNLESS it's a Buslogic Bt445S with a revision less than `D' (BIOS 3.36 or earlier). <1.1.5> 1.1.5 has bounce-buffer support that make all of the above scenarios work with a full 32MB of memory or more. You are therefore advised to simply pull 16MB of memory out, install, and then see about upgrading to FreeBSD 1.1.5 so that you can put it back.
