An advanced BIOS for OpenComputers. There are two ways to install/update:
- Run
update/install.lua - Using the Zorya BIOS Update option.
The Zorya BIOS comes built in with support for booting OpenOS, Plan9k, and Tsuki Kernel. Other OSes can install their own boot modules. The BIOS also has support for network booting and booting Netinstall scripts. Also OEFI compliant.
Zorya is almost OEFI complient. Report any problems with OEFI.
OEFI library support:
| Method | Status | Notes |
|---|---|---|
oefi.getApplications() |
Supported | |
oefi.getAPIVersion() |
Supported | Returns 1. |
oefi.getImplementationName() |
Supported | Returns Zorya BIOS |
oefi.getImplementationVersion() |
Supported | Returns the version of the Zorya bootloader |
oefi.returnToOEFI() |
Implemented | Will forcefully reboot. |
oefi.execOEFIApp(drive, path) |
Supported | |
computer.getBootAddress() |
Sometimes supported | Only defined when booting OpenOS or a similar OS. Tsuki kernel does not have this set. (It uses the bootaddr argument.) |
computer.setBootAddress(addr) |
Supported | Does nothing. |
Zorya also extends OEFI with a few extra methods:
| Method | Returns | Notes |
|---|---|---|
zorya.getEntries() |
table |
The table contains the raw data of the zoryarc boot entries. |
zorya.addEntry(name:string,handler:string,fs:string,...) |
nothing | Adds an entry to the zoryarc file. |
zorya.getVersion() |
number |
The same as _ZVER |
zorya.getEntryID() |
number |
Returns the entry ID of the booted entry. |
zorya.removeEntry(id:number) |
nothing | Removes an entry from the zoryarc file. |
zorya.getMode() |
string |
Returns zorya, oefi, compat, fallback, or error |
Note: Only zorya.getMode() is available in fallback mode.
"Zorya mode" is when Zorya has booted straight from a Zorya module (such as p9kboot or tsukiboot). This has the entire Zorya library available and also provides the OEFI library
OEFI mode is when Zorya has loaded an application from the OEFI module. This may result in instability as Zorya is not 100% compliant. Also provides the Zorya library.
Compatibility mode is engaged when Zorya loads an OS from init.lua. This disables the OEFI and most of the Zorya libraries. Mostly used for OpenOS and compatible OSes. Still may expose advanced features to the OS via virtual devices (overriding the component library)
Fallback mode is when Zorya fails to load modules, and still has the BIOS pointing to a device. This will only load from init.lua and tends to boot much slower. Only intended to be used to fix Zorya.
This is when Zorya has encountered an unrecoverable error. Usually, it will try to enter the OEFI terminal. If it can't, it will let the machine handle the error.
Zorya supports booting OEFI apps. Be warned, it may still be buggy.
