### Question 1: Meaning of `/E` and `/L` parameters
- `/E`: Usually, in the context of extracting files from a cabinet (`.cab`) file, `/E` means "extract" (extract files from the cabinet).
- `/L`: `/L` is used to specify the destination directory where the extracted files will be placed. Here, `%RAMDRIVE%\SYSTEM` is the destination directory specified by the `/L` parameter.

### Question 2: Meaning of `>NUL`
- `>NUL` is a redirection in batch processing. It redirects the standard output of the command to the null device. This means that any output that the `EXTRACT` command would normally produce (such as status messages or error messages) will be suppressed and not displayed on the screen.

### Question 1: Meaning of `/E` and `/L` parameters
- `/E`: Usually means "extract" in the context of extracting files from an archive. For example, in commands related to extracting files from a cabinet (`.cab`) file like this one, it indicates that the operation is to extract the contents of the archive.
- `/L`: Specifies the destination directory where the extracted files will be placed. Here, it is set to `%RAMDRIVE%\SYSTEM`, so it tells the `EXTRACT` command to extract the files to the `SYSTEM` directory within the drive represented by the `%RAMDRIVE%` variable.

### Question 2: Meaning of `>NUL`
- `>NUL` is a redirection operator in batch scripting. `NUL` is a special device in Windows that represents the null device. Redirecting the standard output (in this case, the output of the `EXTRACT` command) to `NUL` means that the output of the command will be suppressed, i.e., no output will be displayed on the screen.

Why do I want to use a flash drive under DOS, but when booting to load the USB driver, it just stops and isn't a system crash. What's the reason for this?
