This is hard to believe, but I found the QNX2 manual that we have and
here’s the deal.
There is a package provided by QSSL called RUNDOS. It has 3 programs
rundos - DOS emulator that lets you run a DOS application within
the QNX2 environment.
qdos - BIOS emulator. QDOS emulates only the BIOS and runs
PC-DOS. PC-DOS must be purchased.
dfs - DOS file system. This provides live access to DOS files
as if they were QNX files, allowing your to use all the
standard QNX utilities directly DOS files
Sooo what you would use just to copy files is dfs. The other 2 programs
let you run programs like MS-WORD on the QNX2 system. It is something
that was purchased from QSSL.
我用的是你EMAIL给我的 dfs utlility, 我用你给我的写盘工具rawwritewin-0.3把你给的印象文件dfsutl写到1.44MB的磁盘中,放到QNX3.21中,用LS 1:/ 命令可以看到A盘中有两个目录:bkup 和utl。两个目录中都有一个dfs文件,我试着都运行了一下,效果是一样的,系统都提示“Unable to create DFS administrator task–Administrator program not found”。
我用cp命令把dfs拷到硬盘中运行,结果相同。
我在ftp://quics.qnx.com/usr/free2/qnx2.21/qnx_utils/dfs 中下载了三个文件,但我不知他是什么格式,用你给的写盘工具,写到A盘中也不能读,QNX3.21报告“Unable to access”.
