Errata
1. A1,B1 - VGA Panning
Problem: VGA text mode diagnostic and stress test applications that use pixel panning can experience temporary
visual anomalies under certain memory configurations. This issue is seen in two test configurations.
1. Test applications using a single VGA font table with a 32KB font buffer range could fail. The
failure can occur using 64MB technology products that use 2KB and 4KB page sizes. This failure
was seen in a diagnostic utility.
2. Test applications using multiple VGA font tables could fail if the first two fonts are from different
tables. This failing condition can occur in any memory configuration. This failure was seen in a
stress test utility.
Implication: Entire scan lines will appear to flicker in some VGA diagnostic and stress test applications. However,
there are no known customer sightings of this erratum. No known end user applications fail for this
erratum.
Workaround: No workaround exists.
Status: There are no plans to fix this erratum in silicon..
2. A2,B2 - VGA Timings
Problem: Some VGA applications, running in 40-column modes that use a non-black border color may experience
color/visual issues on systems configured with certain monitors.
Implication: 40-column VGA modes may experience visual color anomalies on some CRT monitors. This was
observed using VGA focused Intel test software. With certain monitors, colors in active areas may
change as the border color changes. As observed while using the test software, visual color anomalies
can range from a slight color change difference to a blank screen. Based on the lack of customer or end
user reported issues related to this erratum, the number of VGA applications that run in 40-column
modes and also use non-black border colors is low. Based on Intel’s validation and compatibility testing,
the number of CRT monitors that exhibit this color anomaly is also low.
Workaround: No workaround exists.
Status: There are no plans to fix this erratum in silicon
