Synopsis

Name: MSDVersion

Minimum usb8x version: 0.10

Gets mass storage driver version and RAM requirements.

Inputs

  • None

Outputs

  • HL: Size of internal memory buffer in bytes
  • DE: Size of sector buffer in bytes
  • B: Mass storage driver major version
  • C: Mass storage driver minor version
  • A: Size of file handle for opened files

Destroys

Notes

It is probably safe to assume that HL will be 254, DE is 512, and A is 27, but if you want to allocate memory dynamically, this function is important.
