The "Autocheck" entry field corresponds to the /AUTOCHECK:xxx in the HPFS or HPFS386 CONFIG.SYS command line. Here you can determine for which drives OS/2 will automatically perform a CHKDSK at system startup.

Simply enter the respective drive letters here (without the trailing ":"). OS/2 will check each drive that you specify here at system startup if you have not shut down your system properly (for example, after a black-screen crash).

If you specify a plus sign ("+") before a drive letter here, that drive will always be checked, which is not really preferrable.

Example: If you enter "C+DE", drive D: will always be checked, while C: and E: only if needed.

Note: For HPFS drives, the auto-check is absolutely necessary because accessing "dirty" HPFS partitions will result in system errors. You should enter all your HPFS drives here because OS/2 will print error messages at startup otherwise. This applies especially to your boot drive, or OS/2 will refuse to boot altogether if you forgot to shut down or the system crashed.

Press the "Propose" button to have all the HPFS drives of your system added to the entry field.
