/* Deshab CMD — Windows 风格命令行（PE/EXE 兼容层前端）
|
||||
*
|
||||
* 黑底白字 cmd.exe 风格，PS/2 键盘输入。
|
||||
* 内置命令：dir/cd/type/copy/del/ren/mkdir/rmdir/echo/cls/ver/set/help/exit
|
||||
* PE 执行：输入 foo.exe 或 foo → 从 FAT32 根读取 → 调用 UTSM PE 服务执行
|
||||
* - PE32+ (64位)：UTSM 原生 Ring0 执行
|
||||
* - PE32 (32位)：UTSM 内嵌 x86-32 解释器执行
|
||||
* Esc 返回桌面。
