These specifications are subject to change without notice. Manual Revision 2. 0 April 26, 1999 3VBA Features FEATURES 3VBA Features: · 3VBA is based on the Mendocino Processor operating at 300 ~ 466MHz on PGA370. [. . . ] (http://www. 2themax. com/ please visit our Technical Support section for the latest updates) · 3VBA utilizes a Lithium battery which provides environmental protec tion and longer battery life. Page 1 Features 3VBA · Supports the (4) Universal Serial Bus (USB) Ports. The onboard VT82C686A chip provides the means for connecting PC peripherals such as; keyboards, joysticks, telephones, and modems. · Built-in ATX 20-pin power supply connector. · Supports ring-in feature (remote power-on through external modem, allows system to be turned on remotely. · Resume by Alarm - Allows your system to turn on at a preselected time. · Power Loss Recovery - In the event of a power outtage your system will automatically turn itself back on without user intervention. · Supports CPU Hardware sleep and SMM (System Management Mode). · Supports Keyboard power ON function (KBPO). · Built-in AC97 PCI Audio.

The DIMMs can be either EDO (Enhanced Data Out) or SDRAM (Synchronized DRAM). · · · DIMM SDRAM may be 83MHz (12ns), 100MHz (10ns) or 125MHz (8ns) bus speed. If you use both 50ns and 60ns memory you must configure your BIOS to read 60ns. When using Synchronous DRAM we recommend using the 4 clock variety over the 2 clock. Figure 2 and Table 1 show several possible memory configurations using both SIMM and DIMM. DIMM 1 DIMM 2 DIMM 3 DIMM 1 (Bank 0) EDO/SDRAM* 8MB, 16MB, 32MB, 64MB, 128MB, 256MB X 1 DIMM 2 (Bank 1) B ank 0 B ank 1 B ank 2 -S y n c h ro n o u s -E D O Total Me mory DIMM 3 (Bank 2) = 256MB Maximum None None = 512MB Maximum EDO/SDRAM* EDO/SDRAM* 8MB, 16MB, 32MB, 64MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB X 1 128MB, 256MB X 1 None = 768MB Maximum EDO/SDRAM* EDO/SDRAM* EDO/SDRAM* 8MB, 16MB, 32MB, 64MB, 8MB, 16MB, 32MB, 64MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB X 1 128MB, 256MB X 1 128MB, 256MB X 1 * SDRAM only supports 8, 16, 32, 64, 128, 256MB DIMM modules. [. . . ] Using the Soft-Off by Pwr-BTTN feature, you can choose either Instant Off (turns system off immediately), or 4 sec delay (you need to hold the button down for 4 seconds before the system turns off). When the system is in 4 sec delay mode, we has added a special feature to make the system go into suspend mode when the button is pressed momentarily. Page 7 [. . . ]
