End of Interactive Support
Intel is announcing the end of interactive support for the Intel® RC440BX Motherboard. See the End of Interactive Support Announcement for details.
Latest BIOS and drivers
The BIOS identifier for this motherboard is 4R4CB0XA.86A. Check here for the current BIOS version and here for the current drivers.
Audio driver installation
Two issues are known: the drivers are too large for a floppy installation, and those provided on the Intel® RC440BX Motherboard CD-ROM may not install properly on a fresh installation of Windows* 95 or Windows* 98. for details.
Processors supported
The Intel® RC440BX Motherboard supports Pentium® III processors, Pentium® II processors and Intel® Celeron® processors via the 242-contact slot connector. Please see the additional information on supported processors.
Processor considerations
Several processor considerations must be observed to ensure the processor is properly cooled and secured to the motherboard.
Motherboard won't boot - power supply
If the power supply does not provide sufficient current, some system configurations with the motherboard may not power up.
Motherboard won't boot - BIOS settings
The system will not complete POST if you are using BIOS version 4R4CB0XA.86A.0009.P03, and both the Quiet Boot and Quick Boot options are Disabled. The failure to boot does not occur if either of the two settings is set to Enabled. Enabled is the default setting for both options. This issue is expected to be resolved in a future BIOS release.
Motherboard won't boot - repeating 6 beep error code
This beep code indicates that there was a problem during DRAM memory device detection. Check to ensure that system memory is properly installed. Also be sure that the DIMMs you are using are on the Intel RC440BX Motherboard tested memory list.
"SERIAL PRESENCE DETECT (SPD) device data missing or inconclusive."
This error message appears when non-SPD memory is detected during POST or the BIOS cannot determine SPD requirements.
Windows* 95 with CD-ROM or second hard drives
There are two known issues involving CD-ROM or secondary hard drives: The retail version of Microsoft Windows* 95 may not recognize the Intel® 82371EB PIIX4e IDE controller used on Intel® motherboards, causing the BIOS to disable the secondary IDE channel. This can result in IDE devices (such as CD-ROM drives) not being detected or disappearing after the system is rebooted. A utility is available to update the MSHDC.INF file and resolve the issue.
Windows 95 also may fail to recognize a CD-ROM drive that does not comply with the ATAPI specification.
IDE device not displayed during power-up
All IDE devices must be ATA4 compliant and the cable length is limited to 18 inches.
Second serial port
See the second external serial port instructions for advice on how to use the on-board header.
Conflict with PCI bridge and AGP video controller
A conflict with a "PCI standard PCI-to-PCI Bridge" and the AGP video controller in the Windows 95 Device Manager does not affect the functionality of AGP with Windows* 95. The "PCI standard PCI-to-PCI bridge" is actually the Intel® 82443LX Pentium® II processor to AGP Controller, which Windows 95 cannot properly identify.
IRQ9 not available
IRQ9 is not available to assign to ISA add-in cards, because it is dedicated to the power management function of the PIIX4E controller on the motherboard. This is true for other motherboards which use the 82371AB PIIX4E component.
Will my ATA-66 hard drive work on the Intel RC440BX Motherboard?
The IDE controller integrated into the Intel® RC440BX Motherboard supports Ultra DMA modes 0,1 and 2. Ultra DMA mode 2, also known as ATA-33 or Ultra DAM 33, is the highest speed transfer mode supported by the Intel® RC440BX Motherboard. The motherboard hardware cannot support the maximum transfer rate of the ATA-66 drives. A drive that complies with the ATA-66 specification will run timings up to Ultra ATA-33 on the Intel® RC440BX Motherboard. Please refer to the Technical Product Specification and the Motherboard Specification Update for more complete details on the various transfer modes.
