This is a multi-part message in MIME format. ------=_NextPart_000_0037_01C4E362.C8E7C870 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable My interrupt comes every 500 micro seconds. If anyone use HD without = smartdrive interrupts works fine every time if it is 9 (If I use INT 5 = the interrupt gets down to 20 ms). When I use smartdrv some intervals = over two interrupts gets down to 20 ms aprox. I soposed that smartdrv = catch CPU control and not reenable interrupts, then I probe to catch HD = interrupt and enable PIC interrupts (outport(0x20...)) and CPU = interrupts (enable()) but it don't works. It may be possible that = smartdrv disable interrupts. ------=_NextPart_000_0037_01C4E362.C8E7C870 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=3DContent-Type content=3D"text/html; = charset=3Diso-8859-1"> <META content=3D"MSHTML 6.00.2745.2800" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <DIV><FONT face=3DArial size=3D2>My interrupt comes every 500 micro = seconds.
