But what exactly is the issue?
Given that the top 128k of the bios are mapped below 1M there is a high chance that jumping from 128k to 256k causes issues, especially as adding the xhci driver doesn't touch any code path which would actually be executed on a isapc machine ... Didn't investigate in detail. Maybe isapc memory init is different. cheers, Gerd _______________________________________________ SeaBIOS mailing list [email protected] http://www.seabios.org/mailman/listinfo/seabios
