Also known as:

  • Anigma / Solectron / SCI BAT486IP (420ZX)

Known issues:

  • DALLAS RTC coin cell empty

The motherboard's Real-Time Clock (RTC) chip contains a coin cell that may have drained, causing the loss of CMOS settings. This can result in an inability to save settings, causing system instability or failure to boot. To fix this, the RTC chip can be replaced with an equivalent or repaired by cutting into it and soldering on a new external coin cell holder. Replacement guides are available at https://github.com/necroware/nwX287 or https://github.com/necroware/nw12887, depending on the actual chip used.

Notes:

  • Integrated PCI Promise IDE controller with ATA2 support

  • BIOS editor crashes when IDE drive configured > 2.1 GB

  • PS/2 style mouse and keyboard

  • Has additional power plug for PCI power

  • AMD 5x86 identified as "CPU = ??? 100" but functions @ 133 with WB cache

  • Used in Gateway 2000 computers with Part Number MBDPCI003AxWW

  • Aries 486 PCI Non-integrated motherboard
