I/O MAP AND MEMORY MAP
I/O Map
I/O port range used is 250h-257h. Be sure that no other hardware in the system makes use of this I/O
range.
Memory Map
PV-5120 uses no memory range.
PV-5122 & PV5124 uses memory range D0000h-D7FFFh.
Be sure that no other hardware in the system makes use of this memory range. If your system BIOS
set-up has ROM BIOS shadowing functions, you may enable shadowing in the D0000h-D3FFFh range
to improve flashdisk performance. You should not enable shadowing in the D4000h-D7FFFh range. If
your system BIOS only allows to enable/disable shadowing in the whole D0000h-D7FFFh range, you
must disable it.
