### IBM Thinkpad 127 error 고치기 ###
- CPU를 업그레이드 했을 경우 L2캐시 문제로 알려짐(L2 캐시 disable).
When you boot, you get bios post error 127. Then you shoud do the following:
Choose "test",
choose "exit",
choose "config",
hit "ctrl-d", opens bios hex-editor.
Take cursor to (row 20, column 0), key "02" -> "0A",
hit "F2",
hit "esc",
choose "exit",
choose "ok", and reboot.
Next boot should go without error-127
The value at row 20 and column 0 on my ThinkPad 770Z and on Sharedoc's 600E was originally 02(0x02). Here is a diagram indicating where this value should be located:
