For DOS machines, the names are truncated to just the base - tool name, like GCC. - -Installation ------------- - For this beta release, there are three tar files on the tape. A - simple "tar xvf [device name]" will work. One of the tarfiles is - all the sources, the others are binaries. One set is for a HP-UX - host, and the other set is for a sun4 host. - - First, make a directory called /usr/cygnus/beta-941019. Cd into - this directory and type the tar command to extract the three tar - files. Once the tar files are off the tape, you can uncompress - and extract them. Typically, once they are installed, it's common - practice to make a symbolic link so the path - /usr/cygnus/beta-941019 works regardless which host. The actual - binaries are in /usr/cygnus/beta-941019/$host/bin, where host is - the configuration string for this machine. - - - WinBond W89k board - .................. -Downloading ------------ - To download type the "U" command to the ROM monitor.

The 0 is cause the - monitor wants to offset the address in the srecord to 0x40000. The - problem is that it doesn't relocate data right.
