Hi Lee Eric, > Is there any SATA driver available on DOS can access SATA hard drivers?
The short answer is that you do not need one: You may have experienced that older versions of Windows cannot see your SATA drives. This problem does not affect DOS, because DOS simply uses your BIOS to access drives. The long answer is that drivers such as UIDE which Bernd mentioned and which can be found on http://johnson.tmfc.net/dos/driver.html may give you faster than BIOS access to your SATA harddisk. This is as today, the BIOS is often only used for booting, so it can happen that speed is not optimal. This can also be the case for USB sticks, flash drives, memory cards and card readers and other things which you can boot from with a modern BIOS - the speed in particular on USB can be low. Bret Johnson and Georg Potthast both have DOS USB drivers to solve that problem, but I think only Bret's driver can do USB 2.0 speeds. Also, I am not sure whether UIDE works in AHCI mode. I also think no DOS driver yet uses the NCQ system where modern multitasking operating systems queue multiple concurrent read/write requests and let the disk itself decide how to process them in an efficient order. Eric PS: The related xcdrom, gcdrom and gxcdrom drivers, plus maybe again UIDE, also support ATAPI and SATA CD/DVD/BD. ------------------------------------------------------------------------------ Beautiful is writing same markup.
