If you are booting from an HP Ultra3 SCSI host bus adapter and are using ISA/ EISA-based host bus adapters as secondary devices, you must disable the BIOS on all ISA/EISA-based host bus adapters. If you are booting from ISA/EISA-based host bus adapters and are using an Ultra3 SCSI host bus adapter as a secondary device, see your ISA/EISA-based host bus adapter documentation to ensure that the host bus adapter is at the lowest BIOS base address. ISA/EISA-based host bus adapters boot before the Ultra3 SCSI host bus adapters. My computer crashes or displays panic messages at boot time. You may have to boot from the backup kernel created earlier. To boot from the backup kernel, follow these steps: 1. Reboot the system. 2. At the Booting UNIX System... prompt, type unix.orig and press Enter. 3. Your system should now boot from the backup kernel that you created prior to the driver update. My computer hangs during heavy system load activity. You may have to increase the maximum size available for configuration information. To change the maximum size available for configuration information, follow these steps: 1. At the prompt, type the following command and press Enter: cd/etc/conf/cf.d 2. Type ./configure and press Enter. 3. Under the Configuration tunables, select the Miscellaneous System Parameters. 4. Enter the new value for the maximum size of configuration information. 5. After increasing the maximum size of configuration information and then type q to quit. 6. Type Y to update the system configuration files. 7. Type ./link_unix and press Enter to relink the kernel. 8. Type Y to boot from the new kernel by default. 79
