Resources
This chapter describes system resources, such as memory mapping, register
set and default interrupt request assignments.
The table below shows the memory address area used by the ASLP11.
Address
$00000 - $9FFFF
$A0000 - $BFFFF
$C0000 - $DFFFF
$E0000 - $FFFFF
$100000 - $3FFFFFFF
$4000000 - $FFF7FFFF
$FFF80000 - $FFFFFFFF
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.
