Latest BIOS and drivers
The BIOS identifier for the Intel® SE440BX-2 Motherboard is 4S4EB2X0.86A. The current BIOS version and current audio drivers for the Intel SE440BX-2 Motherboard are available. Intel SE440BX-2 Motherboard BIOS or audio drivers are not interchangeable with the Intel® SE440BX Motherboard (and vice versa).
Intel SE440BX Motherboard or Intel SE440BX-2 Motherboard
You can identify your Intel motherboard by the Altered Assembly (AA) number or the BIOS version string.

Secondary IDE change not working
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.
Windows 95 also may fail to recognize a CD-ROM drive that does not comply with the ATAPI specification.
PCI audio and IRQ issues
The Intel SE440BX-2 Motherboard uses one PCI IRQ for audio to function with a PnP operating system such as Windows* 9x. One additional ISA IRQ is dedicated for legacy audio support. Legacy audio support is used for DOS-based applications and games that are SoundBlaster* compatible. Most DOS-based applications and games only use SoundBlaster-compatible legacy audio requiring the use of an ISA IRQ. By disabling the ISA legacy audio support in the operating system the dedicated ISA IRQ is freed, thus using only one PCI IRQ. DOS applications and games that require SoundBlaster audio support will have no audio output if ISA legacy audio is disabled.
Note: PCI interrupts are shareable per PCI specification 2.0 and 2.1.
IRQ9 not available to ISA add-in cards
IRQ9 is designated for the power management feature of the PIIX4E controller.
IDE device not displayed during power-up
All IDE devices must be ATA4 compliant and the cable length is limited to 18 inches. IDE devices that are not selected as auto-detect in the BIOS setup are not displayed as part of the Power On Self Test (POST).
Will my ATA-66 hard drive work on the Intel SE440BX-2 Motherboard?
The IDE controller integrated into the Intel SE440BX-2 Motherboard supports Ultra DMA modes 0,1, and 2. Ultra DMA mode 2, also known as ATA-33 or Ultra DMA 33, is the highest transfer mode supported by the Intel SE440BX-2 Motherboard. The motherboard hardware cannot support the maximum transfer rate of the ATA-66 drives. ATA66 hard drives will only operate up to ATA-33 on the Intel SE440BX-2 Motherboard.
