[comp.sys.ibm.pc] DOS 4.0 boot record - differences since 3.2?

webster@ac.dal.ca (02/01/90)

I'm familiar with the boot record format of disks
up to DOS 3.2.  Does anyone have a description of
the format used by DOS 4.0?  Specifically I am interested
in the file descriptor part.
Thanks,      -chris  <webster@ac.dal.ca>  aka webster@dalac.bitnet
