JdBP 12.8

The interesting article by JdPB listed in the external references suggests a fix for what he identifies as BPB version 7.0. Later he jumps to the conclusion that 0x80 indicates version 8.0 at offset 0x26 for NTFS. However, he correctly identified magic 0x28 as version 4.0, with the common 0x29 also used for version 4.0. Other sources claim that 0x28 differed in the last bytes, and/or that it was used for what is known as the "European DOS 4.0", a multi-tasking DOS created by MS for Siemens.

All sources I'm aware of agree that the magic hex. value corresponds to a decimal version, e.g., the fix suggested by JdPB uses 0x46 for 7.0 (4*16+6=70). In other words, I don't believe that 0x80 is any version 8.0, it would be version 12.8, and that makes no sense. Nothing to do in the article, just be very careful with the given sources, e.g., there were a few hard to spot errors in the FAT article some weeks ago. IIRC the word at offset 0x26 is used as data by the boot code, just DEBUG an NTFS boot sector to check this theory. –82.113.103.164 (talk) 13:52, 20 August 2011 (UTC)[reply]

  • The article BIOS Parameter Block is not about some random kind of parameter block, but about the so called BIOS Parameter Block (BPB), a specific data structure known under this name. The term BIOS Parameter Block is a proper noun and has written in uppercase in the relevant (printed) literature for decades, therefore we should use the uppercase form as well in order to avoid confusion.
