cecobald Posted November 18, 2008 Share Posted November 18, 2008 Something really strange happened to me today ... A friend of mine has an acer laptop with Broadcom wireless lan, so I wanted to change my Intel 3945 A/B/G with his one to get support on my OSX 10.5.5. When I inserted the Broadcom into my laptop it complained of unsupported wireless lan and that i had to remove it and restart, so I did... and VOILA there was no kernel panic anymore (btw. i removed bluetooth and wlan support in the BIOS). So I hope this helps to all with same laptops... Others with unsupported wlan cards and same problem might try to remove the wlan hardware and try to boot... Edit: Well I think I celebrated too soon. While my os loads everytime into the GUI it still freezes when the CPU reaches 100%. Link to comment Share on other sites More sharing options...
MILAN0 Posted November 23, 2008 Share Posted November 23, 2008 Hm... Try to give a load of 100% to HP NX9420 what is gona be? Link to comment Share on other sites More sharing options...
xristos Posted September 28, 2010 Share Posted September 28, 2010 Finally i did it! HP NX9420 working with 2 cores enabled!!! This fix may also work for other NXxxxx series with centrino duo.. My cpu is T2500 2.00GHz os:snow leopard 10.6.4 dsdt patch needed just replace that value with 0x46: Name (C000, 0xFD) Name (C001, Zero) Processor (_PR.CPU0, 0x01, 0x00001010, 0x06) { Name (C002, Zero) Method (CSTH, 0, NotSerialized) { If (LEqual (C002, Zero)) { Store (One, C002) Store (Zero, \_SB.C003.C004.C005) } Store (\_SB.C003.C004.C006.C007 (), Local0) Return (Local0) } Method (INI, 0, NotSerialized) { If (LAnd (And (\_SB.C008, 0x01000000), LEqual (C009 (), 0x04))) { \_SB.ISMI ([color="#FF0000"]0x46[/color], Zero, Zero, Zero) } } Method (PPC, 0, NotSerialized) { Return (C00A ()) } } Processor (_PR.CPU1, 0x02, 0x00001010, 0x06) { Method (PPC, 0, NotSerialized) { Return (C00A ()) } } also here this line added:\_SB.ISMI (0x46, Zero, Zero, Zero): Method (_SB._INI, 0, NotSerialized) { \C009 () C01C () [color="#FF0000"]\_SB.ISMI (0x46, Zero, Zero, Zero)[/color] } sometimes it hangs at the very begining, if you did a hard shotdown previously(pressing pwr button for 5 sec) otherwise it boots and works fine even at 100% of cpu. Edit: 2/10/2010 ok ok that broke usb2 speed! patching hpet section in dsdt and they will work again! Device (C21D) { Name (_HID, EisaId ("PNP0103")) Name (C21E, 0xFFFFFFFD) Method (_STA, 0, NotSerialized) { If (LEqual (C21E, 0xFFFFFFFD)) { Store (0x00, Local0) Store (\_SB.C09F (), Local1) If (LGreaterEqual (\C009 (), 0x04)) { If (Local1) { Store (0x0F, Local0) } } Else { If (Local1) { Store (0x0B, Local0) } } Store (Local0, C21E) } Return (C21E) } Name (C020, ResourceTemplate () { [color="#FF0000"] IRQNoFlags () {0} IRQNoFlags () {8} IRQNoFlags () {11} IRQNoFlags () {15}[/color] Memory32Fixed (ReadOnly, 0xFED00000, // Address Base 0x00000400, // Address Length _Y0B) }) also you must use vanilla iopcifamily.kext or you will get a kernel panic Link to comment Share on other sites More sharing options...
