Data Frog SF2000 BIOS CRC32 Patcher

This tool will recalculate and patch the CRC32 check bits for a modified bisrv.asd BIOS file for the SF2000; only really useful if you've manually modified data outside of the "safe" areas covered by my other tools. If you haven't done your own hex editing of the BIOS, then this tool probably isn't for you! 🙂

IMPORTANT NOTE: This tool will just blindly modify bytes 0x18c to 0x18f of whatever input file you provide; correct usage of this tool is therefore up to you, not me! 🤣


Step 1: Select Your bisrv.asd

Select your bisrv.asd file. You should probably make a backup of the file first, just in case!
