MSIM

/app/msim

​MSIM is a computer simulator based on MIPS R4000. HelenOS mips32-msim target runs on MSIM and, since MSIM now runs on HelenOS, you can run HelenOS within HelenOS.

Running HelenOS in HelenOS

You need to configure your HelenOS build to include MSIM. You also need to transfer a mips32-msim boot image (e.g. ​this one) and MSIM configuration file ​msim.conf onto the system. Either add them under uspace/dist before building the system, or mount them from a disk / virtual disk image (when running in an emulator).

Within HelenOS, change to the directory that contains msim.conf and the system image and run msim. (It can take a while to boot.)
