    Troubleshooting Introduction to Troubleshooting ISL Environment ISL provides the means to load the operating system. ISL also provides an offline platform to execute diagnostic and utility programs contained in the LIF volume on the boot device when the operating system is not loaded. The ISL program is the first program loaded into main memory from an external media (LAN, disk, or tape) and launched by the initial program loader (IPL) routine from the Boot Administration environment.

    Troubleshooting Boot ROM Selftests Boot ROM Selftests Selftests are called by a bootstrap program resident in the Boot ROM. The Selftests initial- ize and test the board computer hardware needed to find and boot an operating system. I/O portions for the console and boot path are tested by the I/O Dependent Code (IODC) for each I/O function.

    Troubleshooting Boot ROM Selftests Hardware Initialization Support Some hardware, such as video circuit initialization and floating RAM positioning, which can not wait for a system to be booted, must be initialized at power-up as soon as possible to prevent improper operation. Go/No-Go Selftest Support The primary objective is to tell the user that the board computer can boot the operating system.

    Extended Selftest The purpose of the extended Selftest is to test those areas of the board computer which are not routinely tested by the power-up Selftest. This includes VMEbus, HP-IB, the real-time clock and timers. The Boot Console User Interface is used to configure operation of the extended Selftest.
