After showing me all the routine cheching (that resoult ok) just get stucked.
I opened it up, and the motherboad is phisically ok.
I think is a BIOS problem, but for this model, according to the service manual, is not possible to change the chip.
Is instead possible, according to the same manual and according to the phoenix 4.0 user manual flash a new bios in without the computer being able to boot.
Just use a crisis recvery disk (and I now have 1) and a boot block jumper, according to them...
But how I should set it for my computer ?
Please help me.
