12.
Problem:
Implication: If hold timing specifications are violated, data corruption may occur. This data corruption may also
Workaround: A BIOS workaround is available to fix the Tco and Slew Rate at optimum values.
Status:
13.
Problem:
Implication: This issue can lead to system hangs using specific System Validation test software, but testing to
Workaround: Allocate a separate surface that is 16 cache lines deep on a 4QW aligned boundary.

Problem:
Implication: Latency or data drop out may occur in the completion of AC97 cycles. Audio cycles may not be

R
Host Interface RCOMP
Depending upon system design and environmental factors, a violation of the host interface hold
timing specification may occur. Root cause is a circuit (RCOMP) designed to dynamically adjust
clock to out delay (Tco) and slew rate on host interface buffers that does not function.

No planned silicon fix.
Blit Hang
On back to back read modify writes with transparency enabled and the destination from the latest
blits hits on the destination from one of the earlier blits, dead lock can occur in the graphics engine.
date has not identified any real-world applications that cause this behavior. Operating systems
tested were Win98 (315 applications), WinNT4 (74 applications), Win95 (92 applications), and
Win2K (32 applications). Validation activity included the use of automated and manual testing of
over 400 applications, stress test software, and benchmark software. Due to the specific sequencing
of events necessary to create the failure, Intel and major OEMs were unable to recreate the
problem during any testing described above.
Fixed in A3 silicon.
AC97 Latency and Drop Out
Cycles from the local cache fill up the command queue causing aperture cycles from the host to be
starved. AC97 cycles are queued with a lower priority than the aperture cycles and can, therefore,

synchronized with video. MODEM operation may drop out entirely during heavily loaded system
operation. These effects may vary by application, user, OS in use, and system load.
No planned silicon fix.
