Thanks for the info.

PC Card Drive:
Is in the control register b8 and b9 not used?

x86vet:
The control register has only 8 bits, b7..b0. When you say b8 & b9, which bits are you asking about?

Was my fault.

What I mean, is it correct when you read the control register b4 show you the status from the drive? Bit is zero is OK or bit is one it have an error.

x86vet:
Control register b4 can be read to determine if the card is present or not.  If it's zero, the card is present.
