Dear Mr. Ollie Lho,
Please find attached a patch to enable Wake-on-Lan for SiS 900 Ethernet
adapter on Linux kernels.
The patch was tested on various SiS mainboards with 963 Southbridge which has
integrated SiS 900 Ethernet adapter. It is used to wake up the mainboards in
a cluster configuration.
The patch is short, applies cleanly against kernel 2.6.8-rc2 and could be
submitted directly to Mr. Linux Torvalds or Mr. Andrew Morton for inclusion
in future 2.6.x kernels.
Thank you in advance,
Best regards,
Andrew D. Balsa
