SCSI floppy drive support

If you need the DOS FAT support, enable the option with make config.
Create the /dev/ entries: mknod /dev/fd0a b 2 1 ; mknod /dev/fd0c b 2 3
The floppy drive should be installed at SCSI 0.
To mount a DOS floppy: mount -t msdos /dev/fdc

To format a floppy with the ext2fs:

add the following in /etc/disktab:

	 TEAC_1440:\
        :ty=floppy:dt=SCSI::rm=600:\
        :se#512:ns#18:nt#2:nc#80:\
        :pa#2752:oa#128:ba#8192:fa#1024:\
        :pc#2880:oc#0:bc#8192:fc#1024:

disklabel -w /dev/fd0c TEAC_1440
mkfs -t ext2 /dev/fd0a

Fixed a leak of inodes.
Upgrade to linux 2.0.30.
allow weak symbols in libc (need to rebuild gcc)

- May 21th

Fixed an important signal bug (blocking read was returning EOF instead of setting errno to EINTR when signaled).
Added the PS2 keyboard/mouse drivers interfaces for X11.
Print probed devices at boot.

PS2 keyboard users: the X11 server should be rebuilt and reinstalled. Instructions are in the README.X11 file.

- May 14th

Fixed the bug which corrupted the file system. (Incorrect cache invalidation during a disk DMA read).
Allow machines with more than 64Mb of memory to boot.
Correctly print the 712 and 715 model types at boot, instead of the "unknown machine type" message.

Supported machines

The PA1.1 family of processors are supported (PA7150, PA7100LC, PA7200). The kernel has actually been successfully booted on the 705, 712/60, 715/50, 720, 725/50, 725/100, 730 and 770 series machines.

715/33 model does not work :(

Wish list

Virtual consoles.
c++ support in gcc.
Rewrite IP checksum functions in assembly.
HPUX file system compatibility.
HPUX commands compatibility.
Port to unsupported hardwares.
Shared libraries.
Little endian ext2 file system.
...

Common problems and FAQ

writing big files via NFS hangs

Try using a 512 r/w size:

mount -t nfs -o rw,nodev,hard,intr,bg,rsize=512,wsize=512 machine:/dir /mnt
The console doesn't display anything after the devices initialization

You probably have an unsupported graphic board. Only the CRX/GRX boards are actually supported, you can check your configuration with the graphinfo tool under HPUX. If this is the case, your only hope before this is fixed is to boot with the console across a serial line.
Can I run HP-UX commands ?

No, MkLinux is not HP-UX compatible, although a SOM loader would be easy to write, HP-UX syscalls and ioctls calls would still not be compatible. The HP-UX compatibility layer is only available within the OSF1 server.
Only 425 Megs of the disk are recognized, although my disk is much bigger

You need to recreate a disk label with proper disk description and partitions sizes. You can do that in single user mode with the disklabel command. If you also need to repartition the root file system, then you need to do this from another MkLinux disk.
