Where is it trying to load it files from??

The NTLDR can boot TWO kinds of "things":
1) an "ARCPATH" pointing to a valid NT/2K/XP/2003 install
2) a bootsector

BOOTPART simply creates a bootsector using the "loading" code of the various Operating Systems and the "address and geometry" data from current (booted from) bootsector.

For DOS 6.22, as said, IO.SYS must be the FIRST file on partition, followed by MSDOS.SYS, and partition type MUST be 06 (BIGDOS).

About DOS files you DO NOT "put them in the ROOT", you let the HP utility do that for you (or the SYS command).

If anything has changed on the position of the file, or if you changed somehow the partition type, DOS 6.22 will not boot anymore.

You DID NOT run :

mkbt -x pe2usb.bin e:

after or during the procedure I outlined, did you?

For DOS 6.22, you need to use BOOTPART (booted from a floppy image) like this:

CODE

BOOTPART REWRITEROOT:C:

(see bootpart's readme.txt for explanation)

Try again with DOS 7.1 files (you have them in your Win98.ima), extract them to a directory and "feed" them to the HP USB utility when formatting the stick, they should have no problems with a "0E" partition.

In some cases, it might be needed to completely "wipe" the first, say, 100 sectors of the stick, before using the HP USB utility (and then disconnect and re-connect the stick, before using it).

You can use a disk editor to "0 fill" the first 100 sectors on stick, or use this procedure, using tools from the DSFOK toolkit:
http://members.ozemail.com.au/~nulifetv/freezip/freeware/

fsz 51200 J:\0file100sectors.dat

(this will create a file 51200 bytes in length filles with digital "00"s on drive J: - a partition on your Hard Disk).

dsfi \\.\PHYSICALDRIVE2 0 0 J:\0file100sectors.dat

PHYSICALDRIVEs are numbered from 0, so if you have just one Hard disk, it will be PHYSICALDRIVE0, and the stick will be PHYSICALDRIVE1
if you have 2 hard disks, they will be PHYSICALDRIVE0 and PHYSICALDRIVE1
and the stick will be PHYSICALDRIVE2

Be VERY careful, you could WIPE another drive by mistake!

when i run bootpart it, this is what mine looks like after formating with HP utility and pointing it to dos files:

Physical number of disk 0 : 23ff4149
0 : C:* type=e (Win95 XInt 13), size= 1018592 KB, Lba Pos 63

Is this an issue???

[ickleric]

Right i tried doing what you said and used Win98se as feed files.

It now works loading DOS from the GRUB4dos menu. Still doesn't work from the boot.ini menu. But at least it works.

Thanks for all your help. Now what i was hoping to do it load the network boot disk (from www.netbootdisk.com) once i had DOS loaded. I have copied the files across including the autoexec.bat and config.sys. But it fails straight away. Anyone managed to get this working this way???

Yes, it is, the "type=e (Win95 Xint 13)" translates to "0E" or LBA FAT 16 filesystem, making use of eXtended int 13.

Such a filesystem will not be accessible/bootable with/from DOS 6.22, as it was developed AFTER the release of the Operating System, the first "DOS" able to use that kind of partition is DOS 7.10, the one that came with windows 95 OSR 2.0.

As said, try using Windows 98 DOS files, you should have no problems with them, but you might also need to use the LBA switch of BOOTPART:

CODE

BOOTPART Win98 LBA C:\BOOTSECT.W98 "Win98 DOS"

Sorry, cross-posting....

You mean you BUILT a network boot floppy from the downloaded files?

I managed to get the netbootdisk working in the end. For some reason i had to swap the IO.SYS file for another version ass when it loaded the boot disk menu it kept freezing the screen (strange). Also had to add the himem.sys file to the root and edit the config.sys and remove the REM for loading the himem.sys.

So i have now got my USB Pen drive with grub4dos boot menu so i can either load WinPE or Netbootdisk. (just as i wanted)

Thanks for all your help.

Happy everything went well.

Maybe, just maybe, you could try using the Dos 8.0 (Windows ME) that "calls internally" HIMEM.SYS:
