Page 114: Moving Your Computer And Peripherals
Moving Your Computer and Peripherals Your personal computer and its peripheral components are highly sensitive machines that can be damaged easily through bad shipping and handling. We recommend that you take the following steps before moving the equipment to another location. Short Move An example of this is moving from one location to another in the same building. -
Page 115: 6-6 Technical Information
6-6 Technical information Microprocessor The 80386SX is a high-performance microprocessor with a 16-bit external data path, up to 16 megabytes of directly addressable physi- cal memory and up to 64 terabytes of virtual memory space. The operating speed of the 80386SX chip is 10MHz in Normal mode and 20MHz in Turbo mode. -
Page 116: Real Address Mode
Real Address Mode In real mode the 386SX microprocessor operates as a very fast 8086, but with a 32-bit extension if desired. Real mode is required primarily to set up the processor for protected mode operation. The segmentation unit shifts the selector left four bits and adds the result to the effective address to form the linear address. -
Page 117: System Interrupts
The 8254-2 timer/counter is treated by system programs as an arran- gement of four programmable external I/O ports. Three are treated as counters; the fourth is a control register for mode programming. System interrupts xteen levels of system interrupts are provided by the 80386SX NMI d two interrupt controller chips. -
Page 118: Rom Subsystem
ROM Subsystem The ROM subsystem has a 32K by 16-bit arrangement consisting of two 32K by 8-bit ROM/EPROM modules. The odd and even address codes reside in separate modules. The top of the first megabyte and the bottom of the last megabyte address space is assigned to ROM (hex OF0000 and hex FF0000). -
Page 119: Direct Memory Access
Direct Memory Access Eight DMA channels are supported DMA controller chips (four channels in each chip) are used to provide eight DMA channels. The DMA channels are assigned as follows: Table 6-5: DMA Channels DMA Channel Channels 0 through 3 are contained in DMA controller 1. Transfers of 8-bit data, 8-bit I/O adapters and 8-bit or 16-bit system memory are supported by these channels. -
Page 120: Table 6-6: I/O Hex Address
The addresses for the page register are as follows: Table 6-6: I/O Hex Address Address generation for the DMA channels is as follows: Table 6-7: DMA Channel 3 Through 0 Note: To generate the addressing signal “byte high enable” (BHE), invert address line AO. -
Page 121: I/O Channel Slots
I/O Channel Slots The I/O channel supports: • Refresh of system memory from channel or microprocessors • Selection of data accesses (either 8- or 16-bit) • Interrupts • 24-bit memory addresses (16MB) • I/O wait-state generation • I/O address space hex 100 to hex 3FF •... -

Figure 6-11: 36-Pin Expansion Bus I/O Channels Math Coprocessor Control The math coprocessor functions as an I/O device through I/O port addresses hex 0F8, 0FA and 0FC. The microprocessor sends OP codes and operands to I/O ports. The microprocessor also receives and stores results through the same I/O ports. -
