AMD GeodeTM GX1 Processor Silicon Revision 8.1.1 Specification Update 1.0 Scope This document discusses known issues of the AMD date, etc. However, the "A" in the 5th character is constant. GeodeTM GX1 processor, silicon revision 8.1.1. Table 1-1 Software can detect this revision by reading the DIR1 Con- provides a summary of the issues. A detailed description of figuration register (see Configuration registers in the GX1 each issue, its impact, and a recommended resolution/fix data book). The value read from DIR1 is 81h for silicon follow. revision 8.1.1. To determine the silicon revision of the device, printed on Silicon errata are tracked separately. This document per- the chip (bottom-side of SPGA, top-side of EBGA) is the lot tains to silicon revision 8.1.1 only. code number. The lot code number for silicon revision 8.1.1 Note: This is revision 8.1 of this document. The change is a 10-digit number with an "A" in the 5th character (e.g., from revision 8.0 (dated May 2002) is in format V8SKA040AG). Note that the other characters of the lot only. No technical changes. code number may change depending upon lot number, Table 1-1.
