I used USBASPI.SYS + DI1000DD.SYS to successfully run my newly bought latest Longking USB flash drive (super stable mini, 128MB)! So cool! But there is also a problem: the original CD that could be used normally, after loading USB, although there is a CD drive letter, the root directory can also be DIR (directory, files are normal), but it cannot be opened, showing that the file is not found!? Very strange! But it can be used with the moderator's super boot disk, I don't know where the problem is? I loaded it like this: (My DOS environment is the moderator's DOS7.10) device=usbaspi.sys device=di1000dd.sys The previous ones loaded HIMEM EMM386 as usual. Ask for advice!
