| 6 | [http://d3s.mff.cuni.cz/~holub/sw/msim/ MSIM] is a computer simulator |
| 7 | based on MIPS R4000. HelenOS mips32-msim target runs on MSIM and, since MSIM |
| 8 | now runs on HelenOS, you can run HelenOS within HelenOS. |

| 11 | |
| 12 | You need to configure your HelenOS build to include MSIM. You also need to transfer |
| 13 | a mips32-msim boot image (e.g. |
| 14 | [http://www.helenos.org/releases/HelenOS-0.4.3-mips32-msim.boot this one]) |
| 15 | and MSIM configuration file |
| 16 | [http://trac.helenos.org/export/current%3A/mainline/contrib/conf/msim.conf msim.conf] |
| 17 | onto the system. Either add them under `uspace/dist` before building the system, |
| 18 | or mount them from a disk / virtual disk image (when running in an emulator). |
| 19 | |
| 20 | Within HelenOS, change to the directory that contains `msim.conf` and the system image |
| 21 | and run `msim`. (It can take a while to boot.) |
