1.4.881 10482 OR 10483 POST ERROR ON 8550 & 8570

Record number: H091270

Device: D/T8550
Model: M
Tip key:
Date created: O91/10/02
Date last altered: A93/10/21

SYMPTOM:
10482 OR 10483 POST ERRORS ARE DISPLAYED ON AN 8550 & 8570
EQUIPPED WITH OEM ADAPTER(S).

PROBLEM ISOLATION AIDS:
OEM ADAPTERS THAT DO NOT OPERATE WITHIN IBM TECHNICAL
SPECIFICATIONS CAN CAUSE MISLEADING ERROR CODES, INCLUDING
10482 OR 10483 FIXED DISK POST ERRORS. THE FIXED DISK FOR
ANY MODEL PS/2 MAY BE SUPPLIED FROM DIFFERENT VENDERS. SINCE
THESE DISKS HAVE DIFFERENT SIGNAL CHARACTERISTICS, IT IS
POSSIBLE THAT SUSPECT ADAPTERS MAY AFFECT ONLY ONE TYPE OF
DRIVE.

FIX:
WHEN A 10482 OR 10483 POST ERROR IS EXPERIENCED ON A PSY/2
WITH ANY OEM ADAPTER INSTALLED, REMOVE THE OEM ADAPTER AND TEST
THE SYSTEM. IF THE SYSTEM FUNCTIONS CORRECTLY WITHOUT THE OEM
ADAPTER, DO NOT REPLACE THE FIXED DISK. DIRECT THE CUSTOMER
TO THEIR OEM POINT OF SALE FOR ASSISTANCE.

NOTE: ADAPTER CARDS, SUCH AS TOKEN RING HAVE ALSO BEEN KNOWN TO
CAUSE 10482 OR 10483 ERRORS. WHEN EXPERIENCING THESE ERRORS,
CREATE A MINIMUM CONFIGURATION. NEXT ADD EACH ADAPTER ONE AT A
TIME UNTIL THE DEFECTIVE ADAPTER IS FOUND.
