5 w w w w Troubleshooting This chapter explains what to do if you have problems with your system after installing an AHA-1510A/20A Series host adapter. If the information in this chapter does not solve your problems, contact your reseller for support. You can also leave questions on the Adaptec Bulletin Board Service (BBS) at the phone number listed in the front of this manual. Operating Problems Problem The system will not boot from the standard floppy drive or hard drive after initial hardware installation. (1520A/1522A only) Action 1 The LED on the host adapter should light up briefly when you power up the system. If the host adapter detects an internal failure, a message is displayed on the screen. Return the board to the place where you bought it for repair or replacement. 2 If the host adapter and SCSI drive LEDs always remain on, the pin-1 orientation of the SCSI cable is probably reversed between the host adapter and the drive. Fix the cable orientation. (See Connecting Internal SCSI Devices on page 3-8.) 3 If the host adapter BIOS message is not displayed on the screen, the system does not recognize the BIOS. a Check for BIOS address conflicts between the host adapter and other option boards. b Try a different BIOS address. Refer to jumper block J9 in Chapter 2, Host Adapter Configuration. c Make sure the host adapter BIOS is enabled. The jumper on pin pair BE of jumper block J9 must be installed (factory default). 5-1 AAAAAAAAAAAAAAAAAASPCAAAAAArtuHoiAAArncAAAArtkAAAe-SAAAn1NAAApt5AAAeuD1AAAcmAAA0aAAANtAbeAAAeu:/AAAr2mAAA1:0AAA15bAAAA/1eAAA1rAAA0S8:AAA4/e4AAA90rAAA94i0eAAA1-AAAs08AAAU04AAA,2AAAsR-AAAe0AAAre0'AAAvsAAA.AAAGCAAAuAAAAAAidAAAeAAAAAAAAAEAAACAAAAAANAAAAAADAAAAAAaAAAtAAAeAAA:PAAA1aAAA1AAAg/AAAe2AAA:9AAA5/AAA9-AAA41AAAAAAAAAAAAAAAAAAAA
