Message-ID: <20021217102357.A16193@chuggalug.clues.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i Sender: owner-freebsd-fs@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.org I am working at the moment using FreeBSD as a replacement for DOS in a PXE booted buildserver enviroment. (It is just too hard to keep a sensible amount of RAM free after load the MS CIFS/SMB stuff and an ethernet driver) However I need to produce a bootable 4GB DOS partition for the next stage of the process. Currently I do this by dd'ing a gzip'd image of such a fs onto the disk. This takes a while, and I would like to use mewfs_msdos and copy in msdos.sys io.sys and command.com. However I need to find some documentation for precisely where DOS expects to find these files. There also appear to be limitations to the fs tuneables that are acceptable I am unable to 'SYS' a 4GB filesystem created with simply 'newfs /dev/da0s2' (SYS used is FAT32 aware). Anybody got a URL for this stuff? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
