That is an odd geometry, but you can use SYS CONFIG to patch some
settings in the kernel.sys binary itself to make it use only LBA.

See above. Apparently CHS was more compatible in some cases...

And I hope that SYS CONFIG will set both initdisk and higher level I/O.


All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security 
threats, fraudulent activity, and more. Splunk takes this data and makes 
sense of it. IT sense. And common sense.
