LS should be to change (fd0) to (hd32) bar.


Thanks to brother z640919a, after changing to hd32, I finally got the ISO to boot.
Now I want to ask, if I format the USB drive as USB-ZIP, how should I write MENU.LST?

title Run Test
map --mem (fd0)/BOOT/grub/test.iso (fd0)
map --hook
chainloader (fd0)
boot
If I write it like this, an Error1 will pop up.

title Run Test
map --mem (hd0,0)/BOOT/grub/test.iso (hd32)
map --hook
chainloader (hd32)
boot
If I write it like this, an Error21 will pop up.
Just don't know how to write it?

My most hopeful breakthrough for this function is that the ISO does not need to be stored continuously.

Hehe, after all, it is quite troublesome for a very large ISO file to be stored continuously sometimes.

It seems that most files on NTFS - formatted disks are stored continuously.

So if you want to use this function, you can try putting the ISO file in an NTFS partition.

contig.exe is a very useful thing.

This program is also best to have one ready. Always keep some needed files stored continuously.

Version 11-29 fails to boot the ISO file and shows Error 25: Disk read error. Version 11-24 boots the ISO file normally. This change is not ideal.

I used the new version to boot a LINUX CD image booted by GNU GRUB, but it couldn't boot and froze! Also, the previous version could boot ISOLINUX.BIN, but now it doesn't work either. So depressed...


Can GRUB reference ISOLINUX.BIN?
How to achieve it

I tested GRUB.EXE versions 11-24 and 12-01 again. Neither supports Chinese, and it shows error 15 when booting any format file.

GRUB4DOS 12-01 supports Chinese here.

title Lao Jiu 32M Simplified Version [ISO Emulation]
find --set-root /32MPE.iso
map --mem /32MPE.iso (hd32)
map --hook
chainloader (hd32)
The real disk (hd0,7)/32MPE.iso. Boot successful

title Mini System WinPE [Lao Jiu 32M Simplified Version]
map --read-only (hd0,6)+1 (hd0,0)
chainloader (hd0,6)/WXPE/LAOJIU
This can also boot successfully. But shortly after loading the PE image, the following error occurs:

An unexpected error (769) occurred at
Iine 5709 in d:\srvrtm\base\boot\setup\setup.c.
Press any key to continue.
After pressing Enter, it can boot successfully. (2007-11-11) The previous version had no this problem

GRUB4DOS 12-01 supports Chinese characters here.

The problematic one is GRUB.EXE, not GRLDR.

The problem still exists in the 12-02 version. GRUB.EXE can be started. Why is it normal for hard disk boot but not normal for FAT format? It seems that GRUB.EXE cannot enter the directory, so it cannot load the files inside. Through testing other versions, only the versions before 11-11 can be used.

For the grub for DOS version 12.02, when booting the Shenshan Hongye ISO, the boot menu can appear, but after selecting the first item in the menu (which is the Shenshan Hongye PE), it just hangs on a black screen. It's USB drive boot, and this is the case whether the ISO is on the hard drive or the USB drive.

Before that, version 11.29 on my IBM T40 had the error 25: DISK READ ERROR. Now this error is gone, but there's still the above problem.

Version 12.02 GRUB/MBR USB boot, using "Shenshan Hongye PE Toolkit Chang'e No. 1 Commemorative (Formal Version) +"

title ISO
map --mem (hd0,0)/PowerMiniPEV30+.iso (hd32)
map --hook
chainloader (hd32)
boot

Can correctly boot the first item. Did the above person miss a " --mem"?

But when the ISO file is relatively large, such as 6XXM, the error "Error 28: Selected item cannot fit into memory" will occur. My notebook has 512M of memory. Is it because the memory is too small?
