8 years ago What steps will reproduce the problem?
Using Easy2Boot v1.54 on QEMU, VBox and most computers works OK.
On a few computers with an AMI BIOS, it gives an error during
\_ISO\e2b\grub\menu.lst.
All these systems show the same problem and all have AMI BIOS (e.g. 2012)
HP Compaq dx2400 microtower
Asus M4A89GTDPRO-USB3 motherboard
Asus x550ca
\menu.lst is:
#this is only to prevent the grub4dos default menu from appearing for a brief
second!
clear
if "%grub%"=="" if exist (bd)/_ISO/e2b/grub/E2B_GRUB.txt set grub=_ISO/e2b/grub
if "%grub%"=="" if exist (bd)/grub/E2B_GRUB.txt set grub=grub

This executes OK. grub variable is set OK.

all variables - e.g. grub and ?_BOOT are lost when the PROBLEM HERE line is
executed.
USB drive is SDD - (hd0,1) contains a small, unformatted partition:
Partition 1 SIZE=228933.063MiB Type: 07 NTFS *ACTIVE*
START POS = CYL:0 HD:32 SEC:33 END POS = CYL:1023 HD:254 SEC:63
START (LBA) = 2,048 (00000800) SIZE (LBA) = 468,854,914 (1BF22882)
[End=468,856,961]
Partition 2 SIZE=0.031MiB Type: 21 Hidden(rsvd)
START POS = CYL:1023 HD:254 SEC:63 END POS = CYL:1023 HD:254 SEC:63
START (LBA) = 468,856,962 (1BF23082) SIZE (LBA) = 63 (0000003F)
[End=468,857,024]
Partition 3 SIZE=0MiB Type: 00
START POS = CYL:0 HD:0 SEC:0 END POS = CYL:0 HD:0 SEC:0
START (LBA) = 0 (00000000) SIZE (LBA) = 0 (00000000)
Partition 4 SIZE=0MiB Type: 00
START POS = CYL:0 HD:0 SEC:0 END POS = CYL:0 HD:0 SEC:0
START (LBA) = 0 (00000000) SIZE (LBA) = 0 (00000000)
What is the expected output? What do you see instead?
This is a bug in the AMI BIOS.
Perhaps a CPU Register is corrupted?
Code after the last line seems to execute correctly but all variables are
lost/destroyed.
Problem can be 'fixed' using
set PN=
if not exist CD if exist (hd0,0)/%grub%/E2B_GRUB.txt set PN=1
if not exist PN if not exist CD if exist (hd0,1)/%grub%/E2B_GRUB.txt set PN=1
if not exist PN if not exist CD if exist (hd0,4)/%grub%/E2B_GRUB.txt set PN=1
etc.
so that if exist hd0,1)/%grub%/E2B_GRUB.txt set PN=1 is never executed or
other (hd0,4), hd0,5)
What version of the product are you using? On what operating system?
0.4.5c 2014
Please provide any additional information below.
adding debug lines showed variables lost after if exist (hd0,1) line...
Simple test in console (no menu.lst file) did not show the problem - see
