Hello again, Paul, Indeed the problem comes indeed VGA Option ROM. We use different versions. ASRock had modified several times the detection function of the VGA cards and an intermediate version is not compatible with the 2 commits that I had designated. When comparing printable strings from different versions of vgabios, I found the following differences. pci1002,9802.rom from the Wiki use: IBMM intermediate version incompatible with VFCT use: IBM latest vgabios (version ASRock 2.10) use: IBM0 Problem solved. Thank you for your time. Best Regards, Loic _______________________________________________ coreboot mailing list -- [email protected] To unsubscribe send an email to [email protected]
