In this situation, the user had wiped the operating system off the SPARCstation 5 machine and, at that point, was not sure which patches had been applied. The user installed a copy of the Solaris 2.5.1 software and, then, performed the SunPC installation. That solved the problem. SunPC worked without the Accelerator card. The user added the Accelerator card, performed a boot -r, and ran SunPC with no problems.
