I hope I'm in the correct section ... I have Pavilion DV2550ee and the wireless card just went dead. I get an extra wireless card and want to use that on my DV2550. I had searched on bios mod forum and found a modded bios file for my notebook that is SP41959.exe. I tried it and it works BUT the wireless is not initiated/started on boot up. I have to toggle the hard switch to start the wirless (it is ON/OFF switch, not the Fn + F5 button combination). I'm seeking for a helps to mod the bios file by myself. I know I have to hex edit the MOD_5100.ROM part but I don't have the knowledge. Here's the detail of the wireless card ; STOCK/original - Intel Pro wireless 3945 ABG Device ID : PCI\VEN_8086&DEV_4222&SUBSYS_135B103C&REV_02 PCI\VEN_8086&DEV_4222&SUBSYS_135B103C PCI\VEN_8086&DEV_4222&CC_028000 PCI\VEN_8086&DEV_4222&CC_0280 Replacement - ATHEROS AR5B91 device ID (N draft wireless card): PCI\VEN_168C&DEV_002A&SUBSYS_E006105B&REV_01 PCI\VEN_168C&DEV_002A&SUBSYS_E006105B PCI\VEN_168C&DEV_002A&CC_028000 PCI\VEN_168C&DEV_002A&CC_0280 Any helps would be very appreciated.
