Does anybody know how to write device drivers with sector sizes greater
than 512 bytes?  There is a limitation in the PC's BIOS that will not 
allow you to create block devices with sector sizes > 512 bytes.  

This limitation of PC DOS is a real pain in the neck,  I would appreciate 
an answer if someones knows how to circumvent this problem.


Thanks in advance,
