Generally, if you don't have a battery in your machine, there isn't

much point in using this driver and you should say N. If you get

random kernel OOPSes or reboots that don't seem to be related to

anything, try disabling/enabling this option (or disabling/enabling

- 1) make sure that you have enough swap space and that it is

|
- 3) switch on floating point emulation in the kernel and pass
|
|
|
- the "no387" option to the kernel
|
|
|
- 4) pass the "floppy=nodma" option to the kernel
|
|
|
- 5) pass the "mem=4M" option to the kernel (thereby disabling
|
|
|
- all but the first 4 MB of RAM)
|

- 6) make sure that the CPU is not over clocked.
