Hi Jack, > driver, I issue 28-bit commands for up to 28-bit addresses, > while I issue 48-bitters for larger addresses. Runs fine!
I meant if the BIOS only sees the first 2^N sectors and the partition table describes more than that, UIDE will probably not modify the BIOS-reported disk size: So on one side, UIDE could help DOS to access more of a disk than the BIOS, but on the other, that might be unsafe... Eric PS: LBACACHE does treat access beyond 2^32 sectors as a flush event and will not cache the additional sectors. Of course MBR based partitions cannot go > 2^32 either. PPS: What do you think about using Ontrack/Ezdrive style load-before-kernel drivers to map from 4k to 512 sectors? ------------------------------------------------------------------------------ RSA(R) Conference 2012 Mar 27 - Feb 2 Save $400 by Jan. 27 Register now! http://p.sf.net/sfu/rsa-sfdev2dev2 _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
