All things are subject to change at any time.
## Building
Run `./build.sh` inside main directory of repo
Run `./build.sh` inside main directory of repo, however you may first need to run `make toolchain` i would DEFINITELY use more than one job (building GCC takes forever)
To write to a disk, use `./write.sh` WARNING: **is hard coded to /dev/sdb** (sorry i suck at scripting)
@ -43,6 +43,7 @@ You could also run `make all` but the scripts a bit better tbh, it even automate
## How is Testing Done
Testing is mostly done with QEMU These days, but I do sometimes pull out my Dell Latitude D610 to test on real hardware (for anyone wondering its completely maxed out. [2GB of ram Pentium M @ 2.23GHz])
I Also do some testing on a Dell Dimension 8110 (its at my desk 24/7 and has its serial port hooked to my desktop, lol)
## Thanks!
