Old paragraph:
“At system startup time, the IDE device driver is installed as one of the device drivers from the ROM. Note that this is different from the driver loading sequence for SCSI hard drive devices, which are RAM based drivers that are loaded from the device media. Because of this difference the IDE driver cannot be patched out during system startup.”
New paragraph:
“At system startup time, if a RAM-based driver is not found on the IDE drive media, the IDE device driver in the ROM is installed as one of the device drivers. Note that this is different from the driver loading sequence for SCSI hard drive devices, which are RAM based drivers that are always loaded from the device media.”
