A device driver for the  AHA-2940 PCI SCSI Adapter card is provided. This card
houses the AIC-7880 Adaptec SCSI Host Adapter. The macros, <b>INCLUDE_SCSI</b> 
and <b>INCLUDE_SCSI2</b>, must be defined in <b>config.h</b> in order to configure SCSI-2. 
This is a PCI card and <b>INCLUDE_PCI</b> must also be defined in <b>config.h</b>.
<p>
The SCSI-2 driver for x86 requires the AHA-2940 PCI SCSI Adapter card. The 
user is expected to follow instructions on the "Adaptec 7800 Family Manager 
Set User's Guide" regarding installation procedures. 
<p>
The default Interupt Request (IRQ) Channel number used by x86 BSP for
the SCSI interrupt is 0x0a. This may conflict with other interrupts in
the system (Eg. Ethernet). The user can change the macro <b>SCSI_INT_LVL</b>
in file "<b>pc.h</b>" to reflect an interrupt level number that does not conflict 
with the rest of the system interupts. For setting the IRQ number for
the SCSI Host  Adapter the user is recommended to enter the CMOS setup menu.
<p>
If SCSI configuration fails, it can be the result of improper SCSI bus 
termination. Check your hardware setup.
<p>
For information regarding installing the AHA-2940
see the "Adaptec 7800 Family Manager Set User's Guide".

loApicTimer
<dd>

This library contains routines to manipulate the timer functions on the
Intel PentiumPro's Local APIC Timer with a board-independent interface.
This library handles both the system clock and the auxiliary clock 
functions.  The auxiliary clock is either the RTC (real time clock) or
PIT (programmable interrupt timer) channel 0 (define <b>PIT0_FOR_AUX</b> in 
<b>config.h</b>).

i8259Intr
<dd>

Driver for the Intel 8259A Programmable Interrupt Controller (PIC).
<p>
<dt>
loApicIntr
<dd>

Driver for the Intel PentiumPro's Local APIC.
This driver is used in either Virtual Wire Mode (define <b>VIRTUAL_WIRE_MODE</b>
in <b>config.h</b>) or Symmetric IO Mode (define <b>SYMMETRIC_IO_MODE</b> in <b>config.h</b>).
loApicInit () initializes the Local APIC and scans certain memory
regions as specified in the specification to determine the base
addresses.  It uses <b>LOAPIC_BASE</b> and <b>IOAPIC_BASE</b> defined in the BSP, if
it is not able to find the addresses in the MP configuration table.
Scaned memory regions are defined by two pairs of macro in <b>pc.h</b>,
<b>BIOS_ROM_START</b> and <b>BIOS_ROM_END</b>, <b>EBDA_START</b> and <b>EBDA_END</b>.
<p>
<dt>
ioApicIntr
<dd>

Driver for the Intel IO APIC.
This driver is used in Symmetric IO Mode (define <b>SYMMETRIC_IO_MODE</b> in
<b>config.h</b>).  <b><i>ioApicInit</i>(&nbsp;)</b> initializes the IO APIC with information stored
in redTable[].  redTable[] has three entries - lsw, vectorNo, mask.  
First entry, lsw, stores the least significant word of the IO APIC's 
redirection table.  That includes Trigger Mode, Interrupt Input Pin 
Polarity, Destination Mode, Delivery Mode.  Second entry, vectorNo, is
the vectorNo of the redirection table.  Third entry, mask, should be 0 
and used by <b><i>ioApicIntLock</i>(&nbsp;)</b> and <b><i>ioApicIntUnlock</i>(&nbsp;)</b> to hold the interrupt
mask status.

<b><a href="../../ref/pcmciaLib.html#top" >pcmciaLib</a></b> and pcmciaShow
<dd>

Drivers for PCMCIA. In order to use any PCMCIA card 
the <b>INCLUDE_PCMCIA</b> directive
must be enabled in <b>config.h</b>. These drivers currently
support three cards. To use an ATA PC card, enable
<b>INCLUDE_ATA</b>; to use an SRAM PC card, enable <b>INCLUDE_SRAM</b>;
to use a 3COM Etherlink III PC card, enable <b>INCLUDE_ELT</b>.
By default, all three cards are enabled when <b>INCLUDE_PCMCIA</b> is enabled.
