style='font-size:12.0pt'>Nice to have your support. I get the serious problem
on flashrom 0.9.2 on our server systems. We always have to run 3<sup>rd</sup> party
manager application to call up flashrom for BIOS upgrade. However, flashrom
would be failed on “<b><span style='font-weight:bold'>Verifying flash</span></b>”
step because some of <b><span style='font-weight:bold'>programmed data</span></b>
in flash part is different with ones in golden ROM image file on <b><span
style='font-weight:bold'>random offset addresses</span></b>. This defect occurs
on Red Hat 5 x64, SLES 10 x64 and SLES 11 x64. If I run flashrom tool manually without
this 3<sup>rd</sup> application, it would always flash SPI part successfully. Due
to the 3<sup>rd</sup> party application is confidential, it can not be provided
to you for defect reproduction.<o:p></o:p></span></font></p>
