Hi HPA! The boot sector takes a BIOS drive number of the to-be-booted drive from the MBR, which can take it from the BIOS. There also are patches to take the MBR item by pointer from the MBR, but those are not used by default. So I guess the kernel could take the drive number from a boot sector,

Hi HPA and Joao, support for EXT3 in the kernel would indeed be large/complex. Only supporting EXT3 READS already would take circa 10 kB of code, taking the size of the EXT2/3/4 GRUB module as example. I like MEMDISK bootable ramdisk style: MEMDISK can be booted by boot loaders which are able t

The only problem with virtual box is that it isn't accessible. Any folks using screen readers are likely to need dosemu instead of virtual box. It may work under orca, but I've not tested that here. Just a point of interest for those who need/want to know. ---

The basic idea is to start with a fresh install of an Ubuntu LTS server. Then a Script could install all the rest. I am already doing this on a project and it works very well, all scripts are posted on github: https://github.com/alainm/nfas (sorry, it's in portuguese due to local colaborators)

I am interested in writing a new driver, one that would allow you to boot and run dos on a EXT3 partition. In your other message you said that ETX3 was a multithreaded fs. In that case it would be wiser to first add multithreaded support to the FreeDOS kernel. It will be hard, but well worth th

Maybe, but ext3 was designed as a multithreading FS. The multithreading becomes single threading so performance would far worse, and possibly even worse than FAT16/32 or ext3 over redirector. On Fri, Aug 14, 2015 at 3:00 PM, Till wrote: > > Quoting João Jerónimo : > >> Wouldn't it be better to u
