bits, a current M48T02 will store the NVRAM data, but the RTC will not function correctly and the system may fail to auto-boot. Due to incompatibilities with modern M48T02s, it is common to modify failed NVRAMs by cutting into the encapsulation and patching in a new battery. It is also possible to replace the entire encapsulation, which also contains a 32.768 kHz clock crystal. Operating systems The following operating systems will run on a SPARCstation 2: SunOS 4.1.1 onwards Solaris 2.0 to Solaris 7 (sun4c dropped in Solaris 8) Linux - Some, but not all, distributions supported this sparc32 sub-architecture; it had support in Debian from Debian 2.1 (March 1999) through Debian 4.0 (etch), last updated in May 2010. NetBSD/sparc32 since 1.0 OpenBSD/sparc32 - All versions up to 5.9 (OpenBSD 5.9 was the last release to support SPARC32) See also SPARCstation SPARCstation IPX, an architecturally similar machine in a lunchbox form factor References Sun workstations SPARC microprocessor products
