No. LFN as such are not possible on standard ISO9660 or HighSierra CDs. There
is a Juliet format to support LFNs, but it works (poorly) under Win95 only. Of
course, you have the RockRidge extensions for the ISO CD format, but I haven't
seen any DOS software to support them. The ISO format allows for 31.31:3 (? - 
I'm not sure about the 3rd number - it is used to implement the file's
"version" number) and nothing more. A device driver installed with the
DRIVER.SYS interface is nothing more than a physical device driver - the
logical FS routines may be built into it, but they don't have to.
