+This is the multiple IDE interface driver, as evolved from hd.c.
It supports up to 9 IDE interfaces per default, on one or more IRQs (usually
14 & 15). There can be up to two drives per interface, as per the ATA-6 spec.
--------------------------------------------------------
"hdx=" is recognized for all "x" from "a" to "h", such as "hdc".
-
+
"idex=" is recognized for all "x" from "0" to "3", such as "ide1".
"hdx=noprobe" : drive may be present, but do not probe for it
-
+
"hdx=none" : drive is NOT present, ignore cmos and do not probe
-
+
"hdx=nowerr" : ignore the WRERR_STAT bit on this drive
-
+
"hdx=cdrom" : drive is present, and is a cdrom drive
-
+
"hdx=cyl,head,sect" : disk drive is present, with specified geometry
"hdx=remap" : remap access of sector 0 to sector 1 (for EZDrive)
"idex=base" : probe for an interface at the addr specified,
where "base" is usually 0x1f0 or 0x170
and "ctl" is assumed to be "base"+0x206
-
+
"idex=base,ctl" : specify both base and ctl
"idex=base,ctl,irq" : specify base, ctl, and irq number
to take effect.
"idex=four" : four drives on idex and ide(x^1) share same ports
-
+
"idex=reset" : reset interface after probe
"idex=ata66" : informs the interface that it has an 80c cable
