This is an authentic AOpen AX6BC (Revision 1.3) ATX Motherboard powered by the legendary Intel 440BX chipset. Widely recognized as one of the most reliable and sought-after platforms for period-correct Windows 95, Windows 98SE, and DOS retro gaming rigs, it features an Intel Slot 1 CPU interface and verified Award BIOS version R2.10.
Equipped with 2 legacy 16-bit ISA slots, 5 PCI slots, 1 AGP slot, and 3 SDRAM DIMM slots, this board provides the ideal architecture for running classic 3D accelerators (Voodoo / GeForce) alongside dedicated DOS audio hardware (Sound Blaster 16, AWE32, AWE64).
Intel 440BX Chipset: Renowned for rock-solid stability and high memory throughput across late 90s and early 2000s computing platforms.
Slot 1 Architecture with Retention Bracket: Fitted with factory CPU retention arms to securely hold Intel Pentium II, Pentium III, and Celeron processors (or Socket 370 CPUs via compatible Slotket adapters).
Dual Legacy ISA Slots: Includes 2x 16-bit ISA slots for native real-mode DOS sound card support without emulation issues.
Flexible Expansion: Features 1x AGP (2X/3.3V) slot, 5x 32-bit PCI slots, and 3x 168-pin SDRAM DIMM slots.
Verified Firmware: Fitted with genuine Award BIOS chip running Version R2.10 on Board Revision 1.3.
