I wonder if the caching can be implemented in the El-Torito DOS driver. This driver is used for anything looking like a bootable CD, be it a physical bootable CD on IDE/SATA/SCSI/USB-connected controller, or a MEMDISK-loaded (thus in13 supporting) ISO file. I'll do some benchmarking anyway. Copying from a virtual CD located in system memory, to a SHSURDRV-generated ramdisk. I'll try UIDE, CDRCACHE and LBACACHE. Eric suspected all of them won't have that much use. ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
