FROM THE INTERNET:A problem that notoriously affects older Sun workstations is NVRAM failure. The NVRAM chips in Sun workstations contain: a clock, to keep time when the computer is off memory to store boot device order, serial console modes, etc (in a PC you’d call that the BIOS settings) details about the machine itself: its “host id”, what model it is, an Ethernet MAC address. Sun calls this IDPROM. a battery – the “non-volatile” part of NVRAM is managed here by having a battery keep an SRAM alive Over the years, that battery dies. Unfortunately, because it is packaged as one chip, you can’t pop in a new button-cell – you have to replace the whole chip. This doesn’t just mean your computer will lose the ability to tell time – (entertainingly) the machine will lose it’s IDPROM data – it no longer knows what model it is or what its MAC address is supposed to be.✔️ FAST Shipping, Packaged Professionally with care.✔️ NEXT DAY SHIPPING!✔️ 30-Day Warranty✔️ 100% Satisfaction is Guaranteed!✔️ I have 100% Positive feedback!
