If you use the Preboot Execution Environment (PXE) network boot to install the Solaris 9 4/03 operating environment on a SunTM LX50 system, the network boot might fail. The following message is displayed:
error: Assertion failure: - "rp->flags & RESF_ALT", "ur.c" line 80 The root filesystem is not mounted and the configuration assistant has exited prematurely. Booting is unlikely to succeed. CTL-ALT-DEL may be used to reset the machine. Failover to boot interpreter - type ctrl-d to resume boot
Workaround: Choose one of the following workarounds.
If you do not need to use PXE network boot, follow these steps.
Boot the system by using one of the following media.
Solaris 9 4/03 Installation CD
Solaris 9 4/03 Software 1 of 2 CD
Solaris Device Configuration Assistant (DCA) on a boot diskette
See the Solaris 9 Installation Guide for more information on booting from the Solaris DCA.
When the DCA prompts you to choose a network device, select the appropriate network device to use to boot the system.
If you want to use PXE network boot, disable the serial console in the system's BIOS during the installation. For instructions on how to modify the BIOS on Sun LX50 systems, see the Sun LX50 Server Manual at http://www.sun.com/servers/entry/lx50/documentation2.html.
