<h1>Data Frog SF2000 Firmware Version Checker</h1>
<p>This simple tool will just check an SF2000 firmware/BIOS file against a list of known versions, and tell you which version it is. You can <a href="https://vonmillhausen.github.io/sf2000/#firmwarebios-bisrvasd">learn more about firmware revisions for the SF2000 here</a>.</p>

<h2>Select Your <code>bisrv.asd</code></h2>
<p>Select the <code>bisrv.asd</code> firmware file whose version you want to check. You can find the <code>bisrv.asd</code> file in the <code>bios</code> folder on your microSD card.</p>
