Issue #658 has been updated by Gabriel Turlea.
Hi Angel, Thank you for your response. I turned on all the pcie ports that you mentioned and that did not help. I am very aware of the not using gpio from a different board. Kyosti Malkki was kind enough to help me out with this. So I did create the gpio.c specifically for this board. The superio settings do actually affect whether the card eventually appears once linux boots. It seems to be one of the following: irq 0xf3 = 0x09 irq 0xf4 = 0x64 irq 0xf5 = 0xce Here is the OEM superiotool dump of the GPIOs LDN 0x09 (GPIO 2, GPIO 3, GPIO 4, GPIO 5) idx 30 e0 e1 e2 e3 e4 e5 e6 e7 e8 e9 f0 f1 f2 f3 f4 f5 f6 f7 f8 f9 fa fe val 0d ff 21 20 ff 00 00 00 ff ff ff ff ff ff 09 64 ce 00 00 00 ff ff ff def 00 ff 00 00 ff 00 00 00 00 00 00 ff 00 00 00 ff 00 00 00 00 00 00 00 Here is what I get with coreboot: NOTE: I have tried setting 0xe2 to 0x20, but if I do that 0xe1 changes to 0x01 and 0xe2 changes to 0x00 LDN 0x09 (GPIO 2, GPIO 3, GPIO 4, GPIO 5) idx 30 e0 e1 e2 e3 e4 e5 e6 e7 e8 e9 f0 f1 f2 f3 f4 f5 f6 f7 f8 f9 fa fe val 0d ff 21 00 ff 00 00 00 ff 80 00 ff ff ff 09 64 ce 00 00 00 ff ff ff def 00 ff 00 00 ff 00 00 00 00 00 00 ff 00 00 00 ff 00 00 00 00 00 00 00 Thanks again. ---------------------------------------- Bug #658: asus p5g41c-m-lx pcie discovery of realtek 10ec:8168 https://ticket.coreboot.org/issues/658#change-2360 * Author: Gabriel Turlea * Status: New * Priority: Normal * Target version: none * Start date: 2026-07-14 ---------------------------------------- I have tried to port coreboot to asus-p5g41c-m-lx by using the existing pg541t-m-lx variant. Everything works great except I cannot get the onboard lan realtek 10ec:8168 to be detected by coreboot. The card shows up and works once linux boots. Adding some register values in the overridetree.cb seems to disable the card even in linux. Please let me know what supporting info I should provide.
