CHAPTER 6
Resources
Chapter Scope
This chapter describes system resources, such as memory mapping, register
set and default interrupt request assignments.
Memory Map
The table below shows the memory address area used by the ASLP11.
Table 7: Memory Map
Address Size Used by
$00000 - $9FFFF 640 kBytes System RAM
$A0000 - $BFFFF 128 kBytes Video RAM (if enabled)
$C0000 - $DFFFF 128 kBytes
Used by various PCI ROMs
such as VGA, SCSI, Ethernet
$E0000 - $FFFFF 128 kBytes System BIOS
$100000 - $3FFFFFFF Depends on DRAM Extended RAM
$4000000 - $FFF7FFFF Depends on DRAM
Dynamically used by PCI
devices
$FFF80000 - $FFFFFFFF 512 kBytes System BIOS
Register Set
The following section provides an overview of the registers located in the I/O
address space of the ASLP11.
Note:
The address location of PCI devices such as SCSI or Ethernet are not
described in the following tables because the System BIOS automatically
configures (PnP, Plug and Play) each PCI device to avoid address conflicts.
Many device drivers show the actual address locations after installation and
loading.
