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.
2.2 L2 Cache and Cache Module Connector
The AI5TV supports Pipelined Burst Synchronous Cache 256K or
512K. The P.B. Synchronous Cache boost the system performance 10%
higher than regular Asynchronous Cache.

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.
Each 64-bit memory bank can also be populated by using a DIMM
(Dual In-line Memory Module). The DIMM size can be 8mb, 16MB,
32MB or 64MB. The DIMM types can be FPM, EDO or SDRAM
(synchronous DRAM). Since SIMMs are not available in SDRAM,
DIMMs must be used for SDRAM support.
The following are the important factors for populating the SIMM
sockets:
1. Either M0/M1 or M2/M3 bank can be populated first
2. Each bank should consist of the same size SIMMs
3. Each bank should consist of the same type SIMMs.
ex: M0 and M1 should both be EDO or page mode.
4. SIMMs can be mixed by the bank.
ex: M0/M1 are page mode and M2/M3 are EDO
5. If M2/M3 are occupied, then M5 can not be populated. The reverse
is also true.
Bank0(M0, M1) Bank1(M2, M3) Total Memory
4MB ----- 8MB
8MB ----- 16MB
16MB ----- 32MB
32MB ----- 64MB
4MB 4MB 16MB
4MB 8MB 24MB
4MB 16MB 40MB
4MB 32MB 72MB
8MB 8MB 32MB
8MB 16MB 48MB
8MB 32MB 80MB
16MB 16MB 64MB
16MB 32MB 96MB
32MB 32MB 128MB
Note: Bank0 designates the memory bank populated first which
can be M0/M1 or M2/M3.

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. To make a computer system
PnP, an ISA PnP standard is established and supported by new OSes,
such as Windows 95. Under Windows 95, the system board BIOS
must have ISA PnP extension to support the new ISA PnP cards.
2. Power management
The power management feature provides power saving by slowing
down the CPU clock, turning off the monitor screen, and stopping
the HDD spindle motor.
3. NCR 53C810(AHA7850) SCSI BIOS
NCR 53C810(AHA7850) is a PCI SCSI shipped from NCR
(Adaptec). The BIOS required to run cards with the
53C810(AHA7850) chip is built-in the system BIOS. The BIOS will
automatically detect the existence of an 53C810 (AHA7850) chip
and configure it accordingly.

2.5 I/O Port Address Map
Each peripheral device in the system is assigned a set of I/O port
address which also becomes the identity of the device. There are a total
of 1K port address space available. The following table list the I/O port
address used on the system board.
Address Device Description
000h - 01Fh DMA Controller #1
020h - 03Fh Interrupt Controller #1
040h - 05Fh Timer
060h - 06Fh Keyboard Controller
070h - 07Fh Real Time Clock, NMI
080h - 09Fh DMA Page Register
0A0h - 0BFh Interrupt Controller #2
0C0h - 0DFh DMA Controller #2
0F0h Clear Math Coprocessor Busy Signal
0F1h Reset Math Coprocessor
1F0h - 1F7h IDE Interface
2F8h - 2FFh Serial Port #2(COM2)
378h - 3FFh Parallel Port #1(LPT1)
3F0h - 3F7h Floppy Disk Controller
3F8h - 3FFh Serial Port #1(COM1)
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.
