13. System BIOS May Corrupt Audio Add-In Card EEPROM
P
ROBLEM
:
Audio add-in cards using the Yamaha OPL3-SA2 or OPL3-SA3 audio codec have the same
hardware identification number that is used by the Yamaha audio device integrated on the motherboard. This
causes the system BIOS to inadvertently write information into the audio add-in card’s serial EEPROM during
system startup, thereby corrupting the audio add-in card’s EEPROM contents.
I
MPLICATION
:
The audio add-in card will not operate and no audio will be available.
W
ORKAROUND
:
Disable the onboard audio in BIOS Setup before installing an audio add-in card.
S
TATUS
:
This erratum was fixed in BIOS revision 4A3NT0X0.86A.0062.P06.
14. Windows* 95 Will Not Boot if LS-120 Drive is Only Device on IDE
Channel
P
ROBLEM
:
An LS-120 drive will not be recognized by Windows* 95 if it is the only device on the IDE
channel.
I
MPLICATION
:
If an LS-120 drive is the only device on an IDE channel, a black screen with a cursor blinking
in the upper left hand corner will be displayed when Windows 95 is starting to boot and the system will hang.
W
ORKAROUND
:
The LS-120 drive is recognized when connected as either the master or the slave on an IDE
channel with another device.
S
TATUS
:
This erratum will not be fixed.
15. Advanced Power Management May Suspend System During CD-
ROM Playback
P
ROBLEM
:
ATAPI devices (such as CD-ROM and DVD drives) do not reset the inactivity timer that is used
by Advanced Power Management to determine when to place the system into suspend mode.
I
MPLICATION
:
When playback of an audio CD or a DVD file is the only system activity, the system will go into
suspend mode when the inactivity timer expires.
W
ORKAROUND
:
Temporarily disable the Low-power standby and Shut off monitor options on the Display
Properties, Screen Saver menu. This menu is available from the Windows 95 Control Panel.
S
TATUS
:
This erratum will not be fixed.
16. BIOS Does Not Correctly Size 64 MB or Larger DIMMs
P
ROBLEM
:
Because of an incorrect register setting in the memory controller, the BIOS may not correctly
identify the size of 64 MB or larger DIMMs.
I
MPLICATION
:
Only 16 MB of the memory will be reported by the power on self-test (POST). The additional
memory will not be available to the operating system. This erratum applies only to BIOS revision
4A3NT0X0.86A.0082.P07 and later.
W
ORKAROUND
:
None.
S
TATUS
:
This erratum was fixed in BIOS revision 4A3NT0X0.86A.0088.P09.
