As of now, my OS supports only FAT as my boot-filesystem. How would I go about implementing a HPFS boot sector? Does anyone know of any already written HPFS boot-loaders?

I am thinking of a complete switch from FAT to HPFS(and never back again!)

Does anyone have a HPFS hard drive image(with boot-sector)?

Thanks,

There's docs about HPFS here: http://www.nondot.org/sabre/os/articles

Those articles only describe HPFS, they don't tell how to implement it. Disassembled OS/2 HPFS boot sectors will really help.

Anyone?

?

You can keep asking, but if nobody knows, then nobody knows.

Most OSs in development now use either fat, ext2 or a fs of the developers invention.  I haven't seen many with hpfs as the main fs, so I doubt you'll find too much info out there.

That being said, Linux supports HPFS (read-only, I believe), so you might want to check out those sources.

Also, news:alt.os.development is another good place to ask questions.

I posted on alt.os.development and they point me to nondot! THAT IS ONLY DOCUMENTATION, it doesn't give you a bootsector or tell you how to implement it!

Since I can't find info on HPFS which FS should I use?

one word, XFS

Is XFS bootable and, if so, how would I go about implementing it?

Are there unbootable file systems?

Anyway, yeah, XFS is... and yes, XFS rules

For information, I'd look at SGI's link on XFS (provided by nester, above), and also the GRUB sources, which is a live example of how to boot and read files from the XFS file system.

Try this link:

http://artax.karlin.mff.cuni.cz/~mikula ... ndex-e.cgi

There you can find a HPFS hard disk image and some source code adding HPFS support to Linux.

XFS is still faster, and recovers after crashes better.

Anyone have an XFS hard drive image?
