Biostar M5ALA Ver 1.0 motherboard
AMD-K6-2/300AFR processor installed in the Socket 7 ZIF
CPU heatsink with 12 VDC ball bearing fan and mounting screws
Fan power lead with 4-pin Molex pass-through adapter
One 32 MB PC100 SDRAM DIMM
CR2032 clock battery installed
Not included:
Chassis, power supply, drive bays, standoffs and mounting hardware
Rear I/O shield plate for the case
Drives, IDE and floppy cables, front panel cables, power cords
Video card, sound card and any other expansion card
Additional memory modules and SIMMs
Keyboard, mouse, monitor
Driver disks, manual and operating system
Requires a 20-pin ATX power supply. Requires a video card; there is no onboard
video. The AGP slot is 3.3 V keyed, so AGP 1x and 2x cards fit, and later cards
that are keyed for 1.5 V only will not seat. Memory is EDO or SDRAM to a 128 MB
total across the two SIMM banks and the two DIMM banks. Host bus speed is set by
jumper JP2 using the table printed next to the slots, with 66, 75, 83 and 100 MHz
available; the installed K6-2/300 runs 3x at 100 MHz or 4.5x at 66 MHz. IDE
channels run at ATA-33. The board uses standard ATX mounting holes and a standard
ATX rear I/O cutout. The Award BIOS revision flashed on this board is not stated,
so support for later K6-III and K6-2+ parts is not claimed.
