Indeed... All mainboards and controller cards that I know which have S-ATA connectors do also support S-ATA storage access via int13. More or less the same as with SCSI and with many (S-ATA, SCSI, P-ATA) RAID controllers. However, as always, some BIOSes might be slower than extra drivers. Some BIOSes have certain issues with DOS, for example a high stack footprint or using buffers in the UMB area in a way which is not autodetectable by emm386 and so on... More or less the same class of problems as with SCSI. One funny thing is that sometimes people believe it is hard to remove DOS to install XP... This is not the fault of DOS but the fault of bad/missing S-ATA drivers in XP CD/DVD ;-) Eric PS: Does anybody know a S-ATA controller / mainboard with a BIOS which fails to access beyond the 1st 128 GB via int13? ------------------------------------------------------------------------------ _______________________________________________ Freedos-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freedos-devel
