I'd focus on legacy lpc/isa hardware here. PCI-ish hardware which has such timeouts (sata, usb, ...) typically isn't present in the virtual machine if you care about performance. Or, in other words, the best way to handle the sata link detection delay is to use "qemu -M q35,sata=off". cheers, Gerd _______________________________________________ SeaBIOS mailing list SeaBIOS@seabios.org https://mail.coreboot.org/mailman/listinfo/seabios
