Chapter 2 Hardware Description 2.1 Processor The AI5TV is designed to take a Pentium processor with a bus speed of 50, 60 and 66 MHz. Since the internal clock of the CPU can be multiples of 1.5, 2, 2.5 or 3 of the bus clock, the CPU frequency can be 75MHz to 200MHz.
Chapter 2 Hardware Description 2.3 Main Memory The AI5TV provides two 64-bit memory banks for up to 128MB. Each bank consist of two SIMM sockets, M0/M1 and M2/M3. Both EDO and page mode DRAMs are supported. The size of the SIMMs can be 4MB, 8MB, 16MB or 32MB.
64MB 64MB 2.4 BIOS The BIOS on the AI5TV system board provides the standard BIOS functions plus the following additional features: 1. ISA Plug and Play (PnP) extension Unlike PCI cards which are plug and play, ISA cards require setting jumpers to resolve hardware conflict.
2.6 DMA Channels There are seven DMA Channels available on the system board. Only DRQ2 is used by the floppy controller. In the case that ECP mode on parallel port is used, DRQ1 or DRQ3 will be used. AI5TV Motherboard User’s Manual...
16550 UART compatible. The parallel port supports high speed EPP/ECP mode. The floppy controller supports up to 2.88 MB format. The I/O port addresses of the serial and parallel ports are programmable via BIOS set-up. Each I/O can be individually disabled. AI5TV Motherboard User’s Manual...
