   CPU CPU: Windows: Intel Pentium 90 MHz or faster* Linux: Intel Pentium 90 MHz or faster* *Windows and Linux versions are operative only on IBM PC-AT machines with an Intel or an Intel-compatible CPU and is not on Cobalt Qube products with MIPS CPU. (Cobalt Qube 3 is fully supported.) Before using it, please confirm your operation environment Memory Recommended: 64 M byte or more Minimum: 32 M byte [A guideline for comfortable operations] 50 users version: 64 Mbytes or more 100 users version: 128 Mbytes or more * 'Cause Windows 98 is not designed to serve as a server,there may be a case that you cannot operate it properly. In case of an operation with a small number of users and a small number of transactions,where you will shut down Win 98 everyday, it may be operative, but we cannot guarantee its stable operation. We highly recommend to use with Win NT4.0/2000 or LINUX Hard Disk capacity Recommended: 50 M byte or more Minimum: 10 M byte In case of using the File Attachment feature for Bulletin Board 4, WebMail 4, Forum 4, Cabinet 4,Circulation 4 & Web Forms 4, it will heavily depend on the size of attachment files. * In case of using WebMail 4, you will need additional 1 M x number of users.
