Thank you, 1) It is time out, the log is: AHCI/0: probing AHCI/0: link up AHCI/0: send cmd ... WARNING - Timeout at ahci_command:158! AHCI/0: send cmd ... WARNING - Timeout at ahci_command:158!
in line 158(src/ahci.c) is warn_timeout(); 2) If ahci is disabled, the simulator can not find hard disk image. The hard disk image is added as a sata device. 3) The attachment is the log of seabios stage. Thank you again!
