LASI Installation from ZIP File The LASI CAD System has been developed to do integrated circuit and device layout on almost any IBM compatable personal computer. It may be installed by following these 4 steps: 1. Create a subdirectory named "\LASI4" on your hard disk, directly under the root directory. 2. Uncompress and copy the files in LASI41A.ZIP, LASI41B.ZIP and LASI41C.ZIP into the \LASI4 subdirectory, using PKUNZIP or similar program. 3. Add the path "disk:\LASI4" to DOS using the "PATH" DOS Command, where "disk" is the hard disk's letter name. 4. Run the LHI.EXE help program by simply typing "lhi" while in any directory on the hard disk. This will let you conveniently read the help text. If you are new to LASI and want to try it out, read the Basic Information Introduction and follow its instructions.
