Sample TextI used XCOPY and COPY under pure DOS to copy the system disk to the hard drive, wanting to install from the hard drive, but I still can't copy all the contents of the system disk over. I don't know why. Please advise!!

Reply #2, is SYS a command? Could you explain it more clearly? Thanks [ Last edited by chenxing0711 on 2007-11-3 at 09:59 AM ]

Original DOS system situation: There is a program A running normally, generating data and storing it in a file A. Design requirement: Now there is a board using an 8253 for timer interrupts, and it is connected to IRQ3; the interrupt can be generated normally. Now I have written a TSR program and want to use the IRQ3 interrupt to operate on file A. I used ctrl+break interrupt to simulate file operations inside the interrupt, but it keeps crashing. I hope capable friends can help solve this together; I am willing to offer one month's food expenses as a reward! QQ:36014789
