Known Issues & Important Notes
9.10
PCI Slots D323x-S [New]
Possible issue: PCI slot of D3231-S does not operate as expected  Please install BIOS ≥ R1.18.0
General note: D323x-S support 5V-only and 3.3V/5V universal PCI cards.
Mainboard signal level is 3.3V (=5 V tolerant)
3.3V-only PCI cards can NOT be used (different mechanical connector layout)
Since the current Intel chipsets do not natively support PCI any more, D323x-S use a Pericom
PI7C9X118SL PCIe to PCI Bridge which is compliant to PCI Rev. 2.3 (32Bit/33 MHz).
There are several "older" PCI cards that comply to PCI Rev. 2.1 or earlier only. These cards may NOT be supported on D323x-S.
9.11
PCI Express Slots [New]
Possible options to get critical PCIe cards working:
 Reduce PCIe link speed in BIOS Setup
 Use BIOS ≥ R1.20.0
 Change Link State Power Management setting within Windows OS
Control Panel / Power Options / Change Plan Settings / Change advanced power settings / PCI Express / Link State Power Management
Change from "moderate power savings" or "maximum power savings" to "Off".
Note: With BIOS 1.20.0.SR1 and later the PCIe power management settings are changed so that the OS cannot re-enable them even
though they are disabled by default in the BIOS.
