I think it's meant to be a ``WD1007'' disk driver (though it also supports the WD1003-style controllers, but only with a slight hang at boot time in timing out the READ PARAMETERS command). The WD1003 was the original PC/AT MFM controller, and our ancient IDE interface is register-compatible to it. The WD1007V (ESDI) controller added the READP command, and that's all until the recent invention of EIDE and its new hackarounds for the limits of the WD1003/7 interface. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
