Puppy works fine.
I tried to modify grub config, but still Xp wont boot.
Any idea how?

This is original created grub menu.list:

# Other bootable partition config begins
title Windows (on /dev/sda2)
map (hd0,0) (hd0,1)
map (hd0,1) (hd0,0)
rootnoverify (hd0,1)
makeactive
chainloader +1
# Other bootable partition config ends
# Other bootable partition config begins
title Windows (on /dev/sda3)
map (hd0,0) (hd0,2)
map (hd0,2) (hd0,0)
rootnoverify (hd0,2)
makeactive
chainloader +1
# Other bootable partition config ends
# Linux bootable partition config begins
title Linux (on /dev/sda4)
root (hd0,3)
kernel /boot/vmlinuz root=/dev/sda4 ro vga=normal
# Linux bootable partition config ends
# Other bootable partition config begins
title Windows (on /dev/sda5)
map (hd0,0) (hd0,4)
map (hd0,4) (hd0,0)
rootnoverify (hd0,4)
makeactive
chainloader +1
# Other bootable partition config ends

and puppy works with the ''ro'' argument instead of the ''rw'' at sda4?

Try commenting out all the "map" lines (put a # in column 1).
That hasn't been required since Win95.

And leave the Puppy line alone - the kernel is mounted ro (for fsck amongst other reasons), and automatically switched as part of the boot process.

strange, mine doesn't work read only

Well, I should have said "normally it is ..."
Haven't tried puppy yet, but have been thinking about it - guess this will be a reason to download it and try.

Whoa - hey, I'm impressed !!!.
Have to go find a box I can install it on, but the CD is seriously good on the box I tested on - Celeron, 512Meg RAM.
Had to unload the prism2_pci module and load hostap to get the wireless working, but the distro is *GOOD* for its footprint.

I use Puppy on my duron 750 with 64M of ram but with a full hd install works great. The only Linux that I succeded to install on my old pc, I tried Xubuntu, Slackware, Zenwalk and none finished setup
