I am crazy studing install xp from usb these days.
I have tried many ways and each time failed.

Here, I came out a way to install xp, I am not sure wether it is reliable.

We know we can setup xp installation from floppy disk. Wether it is possilbe to chainloader setupldr.bin which is from xp boot folder (the content is same as $WIN_NT$.~LS, but need disk105 and disk106) from a usb-zip boot flash disk? i386 folder is just on the root of flash disk.

If I made a low-level mistake, you may laugh..

You will fall into compatibility issues, not all BIOSes have an option for USB-ZIP.

For the idea- try to put I386 folder, say in XPPRO folder in root.
Change txtsetup.sif and add :

SetupSourcePath = "\xppro\"
SetupSourceDevice = \device\floppydisk1

Put boot files as described in dosnet.inf floppy sections in root. In the beginning stay as close as possible to the original MS design, then amend step by step. Or you might just download the 6 XP Setup floppies set from Microsoft site and put all the files in root, replacing later on TXTSETUP.SIF with your own.

Not quite sure of "floppydisk1" proper syntax, you may need to experiment.

Thanks to ILKO_T

For making boot file I use bt_folder4.cmd from usb_multiboot_10, what I need to do is just add two files disk105 and disk106, both of them are renamed from disk101 or disk102-104 of boot files.

I will try

Though seemingly unrelated, I guess some info may come from this "Recovery Console" thread:
