Explanation of test results

Certain test results may require a little more explanation. This section will try and give some context to specific test failures.

Error ID

Explanation

BIOS32SrvDirEntryPointHighMem

Service Directory Entry Point is in high memory and hence cannot be used by the kernel.

BIOS32SrvDirEntryLength

Service Directory structure is the wrong size, it should be 16 bytes long.

BIOS32SrvDirRevision

Service Directory revision is not recognised and may not be supported by the kernel.

BIOS32SrvDirCheckSum

Service Directory checksum error.

BIOS32MultipleSrvDirInstances

Multiple Service Directories were found, there should be just one.
