BOOTLOOP

cannot find memory?

cannot print init_ram_page in init.c

finnally find it impossible to work on PD with qemu due to PD’s lack of vmx support

so either changing to bochs or running ubuntu in VMware

damn fuck

why not trying to run pintos simulator on macOS ?

Unix-like with VT-x support

maybe i should just follow the guide provided by JHU or SJTU ?
