ERRATA
1. LS-120 Drive Does Not Work as Expected in Windows* 95
PROBLEM: After restarting Windows* 95 from MS-DOS* mode, the system BIOS does not configure the
diskette parameter table correctly if an LS-120 drive is the only floppy drive in the system.
IMPLICATION: Windows 95 will report the LS-120 drive as a hard drive instead of a floppy drive and will report
a floppy drive available as Drive A. If drive A is subsequently accessed, the system will lock up. The
problem does not occur if a 1.44 MB 3-1/2” floppy drive is also present as either drive A or drive B.
WORKAROUND: None.
STATUS: This erratum was fixed in BIOS revision 4D4KL0X0.86A.0012.P04.
2. Serial Mouse Activity Does Not Wake System After APM Shutdown
PROBLEM: The system BIOS does not recognize activity from a serial mouse as an APM event.
IMPLICATION: The system will not be restored from a power-managed state until keyboard activity occurs.
WORKAROUND: The system BIOS does recognize activity from a PS/2* style mouse.
STATUS: This erratum will not be fixed.
3. Stuck or Depressed Key During POST May Cause System Hang
PROBLEM: The BIOS is unable to detect when a key on the keyboard is stuck or depressed during Power
On Self Test (POST).
IMPLICATION: If a key is stuck or depressed during POST, the system BIOS will continue to read data from
the keyboard, resulting in a system hang condition.
WORKAROUND: None.
STATUS: This erratum will not be fixed.
4. System BIOS Does Not Detect ECC Memory Errors
PROBLEM: The system BIOS does not detect when a single or double bit ECC memory error is identified by
the memory controller.
IMPLICATION: For single bit errors, the error will be corrected based on the memory checkbits. The
corrected data will be passed to the system by the controller, but the error will not be signaled to the system
BIOS.
For double-bit errors identified during run time, no error will be signaled to the system BIOS and the system
will not be halted. The erroneous data will be passed to the system by the controller.
Because these errors are not detected by the system BIOS, they will not be flagged in the DMI log stored in
non-volatile flash memory and the user will not receive information from this log that could be useful in
isolating a failing memory module.
