...er Boot Record INT 13h Hook Routines") is a means for an OS driver to follow a chain of INT 13h hooks, examining the hooks'' vendors and assuming responsibility for hook functionality along the way. For MEMDISK, we guarantee an additional field which holds the physical address for the mBFT. The mBFT is an ACPI table which an OS driver can scan for. The mBFT contains the official MEMDISK Info structure (MDI) which itself includes parameters the OS will want to know about. The mBFT points back at the "safe hook" structure''s physical address so that an OS supportin...

...nd a DSDT or SSDT. It fails to find a DSDT because RSDT doesn't point to DSDT; RSDT points to FACP which points to DSDT. After fixing this problem memdisk-acpi is able to hook the DSDT on VMware. Unfortunately it's unclear to me what we gain by hooking the DSDT/SSDT. How can we access the mBFT? Sebastian

Hi. I'm working on replacing a PXELINUX/MEMDISK loaded DOS based installation image with a PXELINUX/MEMDISK loaded WinPE ISO image. So far everything seems to work well (appending "bigraw" to memdisk solved booting problems on several machines), but I kind of miss the option of using getargs.com to get/set environment variables from the memdisk command line. Is there any way to

...MEMDISK kernel arguments passed by previous boot-loaders. He also needed to support the case for MEMDISK-in-a-MEMDISK type situations, where all MEMDISK kernel arguments could be gathered together and output as a list of DOS SET commands. One way to search for "outer" MEMDISKs is via mBFT and/or INT 13h "safe hook" scanning. To support this, some modifications to MEMDISK were needed to allow the sharing of common structure information to MDISKCHK.COM's source code. Also, one MEMDISK bug was found. If you are currently a GETARGS.COM user and your batch file goes l...

I'm running into an issue which I didn't expect to encounter. When specifying the "nopassany" parameter to hide physical drives, I'm getting different output from ELTORITO.SYS (v1.5, syslinux distro) such that it fails. My intent is a LiveCD functionality with a DOS RAMDISK program taking over as drive C:, meaning either no FAT partitions on harddisks and removable disks
