DK440LX SPECIFICATION UPDATE SPECIFICATION CHANGES The Specification Changes listed in this section apply to the DK440LX Motherboard Technical Product Specification (Order Number 682717). All Specification Changes will be incorporated into a future version of that specification. 1. Revision of External Battery Specification The estimated life of the external battery when the system is not plugged into an AC power source has been changed. Paragraph 3 of Section 1.8.
DK440LX SPECIFICATION UPDATE 5. Change to Main Memory Requirements 256 MB EDO DIMMs have not been qualified on the motherboard and will not be supported. The following changes will be made to the document to support this change: In Section 1.1, Overview, the second bullet under Main Memory will be replaced in its entirety as follows: • Supports up to 512 MB of synchronous DRAM (SDRAM) or extended data out (EDO) memory In Section 1.7.
DK440LX SPECIFICATION UPDATE 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.
DK440LX SPECIFICATION UPDATE WORKAROUND: None. STATUS: This erratum was fixed in BIOS revision 4D4KL0X0.86A.0014.P06. 5. Onboard SCSI Controller Identifies Tape Drive as Hard Drive PROBLEM: The onboard SCSI controller may incorrectly identify an attached SCSI tape backup drive as a hard disk drive. IMPLICATION: The tape drive is not accessible, although it appears in the BIOS Setup Boot Menu. WORKAROUND: None. STATUS: This erratum was fixed in BIOS revision 4D4KL0X0.86A.0018.P09. 6.
DK440LX SPECIFICATION UPDATE 9. System Will Not Boot with Network as First Boot Device PROBLEM: The feature allowing the system to boot from the network is not implemented. After the attempt to boot from a network device selected as the first boot device fails, the system BIOS does not attempt to boot from any additional boot devices specified in the BIOS Setup program. IMPLICATION: If Network boot is selected as the first boot device, the system will hang.
DK440LX SPECIFICATION UPDATE 13. System Using 3-Mode Floppy Drive Cannot Read XDF Format Diskettes PROBLEM: The buffer area that stores floppy drive parameters does not have room to store the speed information to allow a 3-mode floppy drive to read a diskette in the XDF format. IMPLICATION: A system that has a 3-mode floppy drive cannot be used to install a program or operating system, such as PC-DOS 7.0, that is distributed on XDF format diskettes. WORKAROUND: None.
DK440LX SPECIFICATION UPDATE 17. The System BIOS Does Not Release Upper Memory When USB Legacy Support Is Disabled PROBLEM: The upper memory area used to provide legacy support for USB keyboards and mice is not released by the system BIOS even when USB Legacy Support is disabled in the BIOS Setup program. IMPLICATION: Users who need to load drivers or TSR programs in upper memory blocks may not have enough space to load them. WORKAROUND: None. STATUS: This erratum will not be fixed.
DK440LX SPECIFICATION UPDATE SPECIFICATION CLARIFICATIONS The Specification Clarifications listed in this section apply to the DK440LX Motherboard Technical Product Specification (Order Number 682717). All Specification Clarifications will be incorporated into a future version of that specification. 1.
DK440LX SPECIFICATION UPDATE DOCUMENTATION CHANGES The Documentation Changes listed in this section apply to the DK440LX Motherboard Technical Product Specification (Order Number 682717). All Documentation Changes will be incorporated into a future version of that specification. 1. Revision of Section 3.4, PCI IDE Support Section 3.4, PCI IDE Support, will be replaced in its entirety as follows: If Auto is selected as a primary or secondary IDE device (see Section 4.2.
