Dear Lars,

Thanx a lot for the kind help...But unfortunately, after changing the KBD_INIT_TIMEOUT from 1000 to 2000 in the file linux2.4/include/linux/pc-keyb.h, the output still remains same i.e keyboard controller jammed and keyboard not initialised is still there as shown in attached file..

Hello Chhavi,

I had to change a time out value in the PS/2 init code to get my keyboard to
work. In /linux-2.4.x/include/linux/pc_keyb.h I changed  KBD_INIT_TIMEOUT from
1000 to 2000.

Hoping to be of some help!
