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.)
