Creating ALX PC Parts

Creating ALX PC Parts

Warning: This documentation is outdated and may not work with the current version of ALX PC. It is kept for reference only.

Manual creation parts and PC from source code

1. Copy folder alx_pc from expression2 to "Steam\steamapps\common\GarrysMod\garrysmod\data\expression2".
2. Start the game.
3. Get Wiremod tab - Chips, Gates - Expression 2 Tool in hands.
4. Open folder "alx_pc" in e2 editor.

BIOS / Chipset

1. Place e2 chip somewhere with BIOS_Chipset.txt file.
2. Get in hands Plugs tool from Wiremod tab.
3. Spawn one DHDD (its in wiremod tab) what will be used as BIOS ROM.
4. Spawn any prop or entity what will be use as Beep Speaker.
5. Spawn different type of sockets (by right click) for different bus types.
6. Use this information for connect inputs on BIOS:

BIOS / Chipset

1. Place an E2 chip somewhere with the BIOS_Chipset.txt file.
2. Spawn one DHDD (it is in the Wiremod tab) which will be used as the BIOS ROM.
3. Spawn any prop or entity which will be used as the Beep Speaker.
4. Get the Plugs tool from the Wiremod tab.
5. Spawn different types of sockets by right-clicking with the Plugs tool for the different bus types. The socket model can be changed to any model you prefer.
6. Use the following information to connect the BIOS inputs:

Note: Each Plug provides letters from A to H. The letter can be chosen freely, but it must match the letter of the corresponding Plug used as the board. All sockets of the same type must use the same letter. For example, if the PCI socket uses A, all PCI sockets must use A. PCIe sockets may also use A, while all PCIe sockets must use the same letter.

Input	Type	Connection	ALX PC Default
ROM	wirelink	DHDD used as BIOS ROM	—
Speaker	entity	Entity used as Beep Speaker	—
CPU_SOCKET	number	Select the letter of the CPU socket (A–H)	A
PCIE_SOCKET[0-1]	number	Select the letter of each PCIe socket (A–H)	A
PCI_SOCKET[0-3]	number	Select the letter of each PCI socket (A–H)	A
KeyboardSocket	entity	Keyboard socket using a letter from (A–H)	A
Power	number	Power button, can be connected directly or through a socket	H
Reset	number	Reset button, can be connected directly or through a socket	G
NoFanSound	number	Optional. Set to 1 to disable fan sound	0

Power and Reset buttons can be connected directly to the BIOS inputs. Alternatively, they can be connected through a socket, as used in the ALX PC setup.

BIOS Outputs

Output	Type	Connection	ALX PC Default
BIOS	entity	BIOS/Chipset entity	—
BIOS_ID	number	Connect to the selected letter input of all CPU, PCIe, PCI and Keyboard sockets	A
PowerInd	number	Connect to a Wire Indicator or other device	—
HDDInd	number	Connect to a Wire Indicator or other device	—

PowerInd and HDDInd output 1 or 0.

CPU

1. Spawn an plug with model what you used for CPU_SOCKET.
2. Spawn an "CPU.txt" chip on this plug or so.
3. Use this information for connect inputs on CPU chip:

[ coming soon ]

GPU

1. Spawn an plug with model what you used for PCIE_SOCKET.
2. Spawn an "GPU.txt" chip on this plug or so.
3. Use this information for connect inputs on CPU chip:

[ coming soon ]

HDD Controller

1. Spawn an plug what you used for PCIE_SOCKET or PCI_SOCKET.
2. Spawn an "HDD_Controller.txt" chip on board.
3. Spawn 1-4 sockets on board what will be used as SATA ports. If you are building PCI card then max sockets are limited to 2.
4. Use this information for connect inputs on CPU chip:

[ coming soon ]

HDD

1. Spawn "HDD.txt" on some prop or anything else.
2. Spawn an DHDD near it. You can spawn up to 4 DHDD's in default configuration (you can extend that by editing HDD code). Each DHDD can hold up to 1 MB of data.
3. Spawn socket what you used on hdd controller.
4. Use this information for connect inputs on CPU chip:

[ coming soon ]

UNDER CONSTRUCTION* 7. Get Memory - DHDD tool and spawn 1 or more HDD Banks near HDD chip. 8. Spawn one more DHDD for BIOS ROM. 9. Spawn two wire buttons (power/reset) without TOGGLE checkbox. 10. Spawn EGP, Digital Screen. 11. Spawn two wire indicators (Visuals->Indicators->Indicator). 12. Spawn any prop as BIOS Speaker. 13. Spawn Wire Gate "To Character" (connect NullByte on BIOS to Out on this gate). 14. Connect everything between chips using Wiring tool, don't forget connect every chip to BIOS. 15. If everything connected correct - you can boot PC now.

Have fun. :)
