...pothesis that there is a definite transition (i.e., everything below a certain size will work, everything above a certain size fails): fdos_8000KiB works fdos_8125KiB works fdos_8180KiB works fdos_8192KiB works (8MiB) fdos_8200KiB works fdos_8202KiB works fdos_8203KiB works ----------------- fdos_8204KiB loops fdos_8205KiB loops fdos_8208KiB loops fdos_8215KiB loops fdos_8250KiB loops fdos_8500KiB loops fdos_9000KiB loops fdos_9216KiB loops (9MiB) Question: what's special about the transition from 8203KiB to 8204KiB? Both have CHS=8/64/32 and both involve a fractional end cylinder. Alex

Fractional 8203K FreeDOS does work, yet larger values, including non-fr...
