H162412: PC SERVER 315 HANGS AT PROMPT DURING BOOT. SYMPTOM: The System hangs displaying a prompt to select the SCSISelect Utility when the Systems attempts to access the Hardrive or Floppy drive during boot. PROBLEM ISOLATION AIDS: All of the following must be true for this TIP to apply: - The system is a PC Server 315 type 8638 model PJ0/PS0/PSV, or a PC Server 310 type 8639 model 0E4/0E5. - The system is configured with a Adaptec Utra Wide SCSI adapter IBM Option p/n76H5407 FRU p/n76H5408/76H5394 or IBM Option p/n76H3579 FRU p/n12J3094. The Adapter is the Primary Boot Controller. - The Ultra Wide SCSI Adapter's "Reset SCSI Bus IC Initialization" setting in the SCSISelect utility is disabled. (Follow steps 2 and 3 in the FIX section to view this setting) - The ASPI8DOS.SYS ver. used is below ver. 1.26 (36,756 k), and is called from the CONFIG.SYS file using the following syntax: DEVICE=C:ASPI8DOS.SYS Note: ASPI8DOS.SYS is typically located at the root of the C: drive. ----------------------- OR ----------------------- - The "Reset SCSI Bus IC Initialization" is DISABLED and the System is NOT calling a Downlevel ASPI8DOS.SYS. FIX: Note: Proceed with Step 1 thru 7 if the System was configured to call a downlevel ASPI8DOS.SYS. Note: Proceed with Step 2 thru 7 if the System was not configured to call a downlevel ASPI8DOS.SYS. 1- Replace the ASPI8DOS.SYS file located on drive C: with a ASPI8DOS.SYS ver 1.26 (or later) size 36,756 K, located on the Diagnostics diskette as well as on the EZ-SCSI diskettes that ship with the Server. Note: the File on the EZ-SCSI diskette is compressed and therefore requires use of the included EXPAND utility. 2- Power on the system and press CTRL + A when prompted to start the SCSISelect utility, select "Configure Host Adapter Settings" then press . 3- Select "Advanced Configuration Options", press . 4- Highlight the setting to the right of the "Reset SCSI Bus IC Initialization", press , Select "Enabled", press . 5- Press two times. 6- Select "Yes" to save changes when prompted, press . 7- Press , select "Yes" to exit the SCSISelect utility, press any key to restart system. Detail: If the "Reset SCSI Bus IC Initialization" is disabled, any subsequent cold boots will hang the system with the described Symptom. The "Reset SCSI Bus IC Initialization" is disabled during boot if the backlevel ASPI8DOS.SYS is called from the CONFIG.SYS file. Adaptec and SCSISelect are registered trademarks of Adaptec, Inc.
