4 Boot Procedures for 112 MB and 128 MB Configurations

Read this chapter only if your SPARCstation has either of these two configurations:

112 megabytes:

- Two 32-megabyte memory boards (installed as a set in SBus slot 1)

- 48 megabytes of SIMMs (installed in banks 0, 2, and 1)

128 megabytes:

- Two 32-megabyte memory boards (installed as a set in SBus slot 1)

- 64 megabytes of SIMMs (installed in banks 0, 2, 1, and 3)

Considerations for SunOS 4.1.1 and SunOS 4.1.1 Rev B Releases

SunOSTM 4.1.1 and SunOS 4.1.1 Rev B contain deficiencies which make the 112- megabyte or 128-megabyte SPARCstation 2 unable to boot SunOS from a CD-ROM (compact disc-read only memory) or cartridge tape. These deficiencies will be corrected in subsequent SunOS releases.

These deficiencies only affect MUNIX, which is only used during installation. Once the system has been installed, vmunix boots and runs normally without any kind of special remedial action.

Considerations for All Other Operating Systems

Use the boot procedure that is appropriate for your system.
