    6-2 Hard Disk Drive Format A hard disk must be formatted before it can be read from or written to. If your hard disk requires this, you should carry out the following steps: Preformat Normally, the preformat utility is supplied by the system manufacturer. IBM provides this utility in the IBM Advanced Diagnostics diskette.

    6-3 Entering 16MHz Turbo Mode The main advantage of the PPM-1630C 16MHz mini-80386SX main- board over ordinary PC/AT mainboards is its dual clock system. This innovation makes it possible for your computer to operate at either of two clock speeds: 8MHz or 16MHz. Entering 16MHz Turbo Mode The PPM-1630C supports both a software and hardware switch to toggle between 8MHz and 16MHz (Turbo) modes.

    6-7 Technical information Microprocessor The 80386SX is a high-performance microprocessor with a 16-bit ex- ternal 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 8MHz in Normal mode and 16MHz 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.

    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 Interrupt Sixteen levels of system interrupts are provided by the 80386SX NMI and two 8259A interrupt controller chips.

    ROM Subsystem The ROM subsystem has a 32K by 16-bit arrangement consisting of two 32K by &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 0F0000 and hex FF0000).

    Direct Memory Access Eight DMA channels are supported by the system. Two Intel 8237-5 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.
