"Memory is alway precious especially when you loose yours." We have consulted with our staff and outside computer consultants and have some simple recommendations for you. You can change your DOS 5.0 or 6.0 CONFIG.SYS to: device=C:\dos\himem.sys DOS=HIGH,umb FILES=60 buffers=30 You can also change your AUTOEXEC.BAT to: lh C:\dos\share.exe where lh means to loadhigh. You can also loadhigh other programs including your LAN Network software, your mouse driver, etc., simply type adding ld before the program you want to load high, e.g., lh smcplus.com lh client lh lsl DOS will try to load high all the programs in can load high and default to conventional memory (640K) when it cannot. We also recommend that you can use Memmaker in DOS 6.0 which is a helpful tool in managing your memory. We suggest that you can call your LAN dealer for help. They often have someone on staff to help you with this and other support services. Please also check your DOS manual for help on memory management.
