Regarding Issue with FreeDOS.

Anil Nair
Hello All,

We were working on PDOS development particularly interrupt number Int 21/AH=0Eh(Select Default Drive). While testing the PDOS function i came across a particular behaviour in FreeDOS, according to the description given in the documentation "http://www.ctyme.com/intr/rb-2570.htm"

"Return: AL = number of potentially valid drive letters".

When tested using a function PDOS returns,

Booting from Hard Disk...
welcome to PDOS-16
welcome to pcomm

C:\>functest

The return value is x 4 x

C:\>

While testing the same behaviour in FreeDOS,

C:\DEVEL\PDOS\SRC>functest

The return value is x 5 x

C:\DEVEL\PDOS\SRC>

Is this expected? Please let me know if anybody needs more details.

Autoexec.bat and config.sys would likely be useful here, especially to understand the value of LASTDRIVE and to know if any other disk drive drivers are installed (CDROM, SATA, USB, Zip, etc.).

Ideally, everyone matches MS-DOS, so knowing what functest returns there might help.

Louis after testing the application in MSDOS it returned me the value 26.

it would help if you would tell us what PDOS is.


besides this, http://www.ctyme.com/intr/rb-2570.htm states

'the return value is the greatest of 5, the value of LASTDRIVE= in CONFIG.SYS,
 and the number of drives actually present'

and max(5, x) can't be smaller then 5

yes
