Dear MdeModulePkg Maintainer, as was reported earlier in this list there are some problems with a large transfers from/to block devices under gEfiBlockIoProtocolGuid provided by ScsiDiskDxe. It is not a big problem for most SCSI devices but this could be a problem for IDE devices accessed via AtaAtapiPassThruDxe in PIO mode.
This patch introduces a Pcd limited a maximum transfer size for ScsiDiskDxe. This is a simple and transparent solution. Another solution would be to teach AtaAtapiPassThruDxe to split IO requests, as legacy IntelFrameworkModulePkg/IdeBusDxe does, but it doesn't look easy. Thank you.
