computer, neither you nor the operating system will inadvertently modify the contents of the disk. On OS X, this is
easily done with the **chmod** utility.
For example, if you saved the disk named "PC-DOS 2.00 (Disk 1)", it should have been downloaded as "PCDOS200-DISK2.img"
in your Downloads folder, so the OS X Terminal command `chmod -w PCDOS200-DISK2.img` will make it read-only, and
`chmod +w PCDOS200-DISK2.img` will make it writable again.

Under the bottom-left corner of any IBM PC on the PCjs [website](/), you should now see a

Some notes:
* PCjs asks the browser to name the downloaded file **pc.json** instead of **pc.js** because a file with a ".js"
extension may cause the Chrome web browser to block the download. And not all browsers support named downloads;
PCjs will attempt to open a new window/tab if that seems to be the case.
* PCjs may attempt to name the downloaded file **pc.json** instead of **pc.js**, because a file with a ".js"
extension could cause your web browser to block the download.
* Your version of Chrome may also impose size limitations on the download. If nothing downloads, the machine may
be too large for your browser, so try a different browser (eg, Firefox or Safari).
* For browsers that don't support dynamic downloads, PCjs will attempt to open a new window/tab instead. Make sure
you copy the *entire* contents of that window into a file named to **pc.js** (or **pc-dbg.js** if the machine is using
the built-in PCjs debugger).
* Your browser may also impose size limitations on the download. If nothing happens, the machine data may be too
large for your browser; try a different browser (eg, Firefox or Safari) or a different machine.
* If you have modified any floppy disks mounted by the machine *or* any of the machine's hard disks, those
modifications should be saved along with the machine.
