Add a warning that this function only works for strings preceding the first non-string field.
What is a non-string field? If you mean an int field, for example, then that would not have an entry in the string table, so I'm a bit unsure about what exactly the problem is?
https://www.dmtf.org/sites/default/files/standards/documents/DSP0134_3.4.0.p... Table 6 – BIOS Information (Type 0) structure
"Vendor", "BIOS Version" are strings. The are followed by "BIOS Starting Address Segment" is a word which may contain a zero byte or not.
You can not use smbios_string() to find the string "BIOS Release Date".
Best regards
Heinrich
