I'm about to modchip my PS2 but I was looking for a reliable diagram site, I found one that's still in 4:3 where half the links are broken which is just bound to be a dead site in 1-2 years as it always seems to happen.
So I'm just gonna mirror it here:

Debugging pinout info if shit ain't working

CX: PS2 clock signal, the modchip doesn't have it's own oscillator crystal so if nothing is appearing besides og bios, check CX or the Ground/3.3v
SX:
PS1 burned games support, if you can't bootup PS1 games but see the matrix logo then check this pin
A G H I B: PS2 burned games support, if you can't bootup PS2 games but see the matrix logo then check this pin
Y: Region free DVD support, if for whatever reason you're trying to watch anime dvds or something like a degenerate and it's not working, check this pin.

If you see the infinity logo then it means M, N, O, P, Q, T, U, V, R, W, CX, 3.3v and Ground are working just fine.

If you get a black screen, double check the bios pins!
On a slim they typically look something like this:

More handy info:


Boot Hotkeys
There is an assortment of different boot options, if you hold down certain buttons while the system boots, the console will perform different tasks. Here is a list of the functions that I know of:

  1. Circle – Boots ModBo Chip/system into PSX DVD Video mode. This forces the PS2 to either play PS1 games or DVD movies
  2. Triangle – Forces the system to boot the Infinity Manager
  3. Cross – Forces the system to bypass settings and boot to the Sony Browser with the ModBo chip enabled.
  4. Start – This Disables the chip. Once this is done, tap the standby button to reset the system to finish disabling the Modbo chip. To Re-enable the Modbo chip you must place the system into standby
  5. Select – This forces a Fast boot on PS2 games. Basically skipping the startup animation and Playstaion 2 Logo on disc boot
  6. R1 – This boots a homebrew ELF file from the first memory card (mc0:/BOOT/BOOT.ELF)
  7. L1 – This boots a homebrew ELF file from the hard drive if installed (hdd0:/__boot/boot.elf)
  8. To enter the Configuration Menu, hold TRIANGLE AND CIRCLE at power on
