Hi,

Does anyone know what controls the number of retries DOS attempts when a dos
critical error (int 0x24) returns a fail result (AL reg = 3)

When I attempt to open a file on a floppy drive without a floppy inserted, I
have to press Fail two times before DOS (?) gives up. Under DJGPP it appears
to retry 30 times or so before giving up!!!

I have checked this by hooking int 0x24 using borland bcc, and under DJGPP
with pmodedj (rebuilt with int 0x24 redirect enabled). I am aware of the
workaround's however I do need to be able to detect these errors, and select
appropriate handler's in advance. I still dont understand why it retries at
all after it's been told to fail the call by my int 0x24 handler ?

*confused*
Any help welcome.
