...oaded natively as .bs (and dos also as .bss). PS. By the way - there's another "trick" to make dos (at least microsoft versions) to boot from another harddisk - if you set actual physical drive number in its bootsector and as active flag on the respective disk (e.g. 81h instead of 80h). This way there's no need for drive swapping code.

So when you boot from only your hard drive attached, it is the primary and only drive. It loads the master boot record that load the NT Loader boot code that is then configured to load the operating system from the primary partition on the primary drive. When you boot from the USB drive, you make it the Primary drive. You then tell it to load the MBR fromt the secondary drive. The secondary

hi, we've got a server with a 8 port 3ware card and 2 ide system disks. now we'd like to replace the ide disks with scsi disks or sata disks (these also recognized as scsi in the kernel). but we can't boot from it. the problem are twofold. first in the normal case the first scsi host scsi0 id the 3ware card, but grub only see the first 8 disk so if the system disk are sdi and sdj the

...4x) without checking for presence (ah=41). memdisk doesn't implement those (#2). Workaround for #1: only hand reset calls down to the original handler if it is meant for hard disks, too (high bit in dl set). i added the following lines to the Reset code: Reset: TRACER 'R' test dl,80h jnz .passon xor ax,ax ret .passon: [ original Reset code here ] Workaround for #2: I implemented the int13 ah=41,42,43,44,47 and 48 functions (not well tested, though!). If someone is interested in those, i could post the patch. cheers, robert

Good day to all, Gert Hulselmans requested a feature for MDISKCHK.COM that would function roughly like GETARGS.COM[1] by Murali Krishnan Ganapathy: DOS SET command output for 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

Hi, funny or enlightening observation: With my qemu-system-i386 it would work if the detected Heads/Cylinder and Sectors/Head factors would change positions ! The effective read operation seems to use H/C = 32 , S/H = 63. The correct LBA would be addressed by H/C = 63 , S/H = 32. -------------------------------------------------------------------------- Reasoning: I have transplanted the
