China DOS Union

Today, I made a GHOST backup and restore program img image. I boot into DOS 7.1 through Grldr (downloaded from the provided network disk) to operate. It runs normally on more than a dozen ordinary desktop computers with different hardware configurations and operating software. It also runs normally on a server with a MSI E7505 motherboard. Only when running on the newly purchased workstation does a problem occur. The phenomenon is that I can successfully enter DOS, but the keyboard is invalid, and all the indicators only flash once at the beginning of the boot and then go out, as if it is not powered on. Changing the keyboard is ineffective. Booting DOS using a floppy disk or CD-ROM is without problems.

I once disabled USB in the BIOS, but the problem remains.

The main hardware of this machine is: Super Micro (SUPERMICR) X6DA8-G2 Intel E7525 Dual Xeon motherboard, Adaptec SCSI v4.30 BIOS, dual P4 Xeon 3.0D, 2G DDR2II400 memory, 160G SATA + 200G SCSI 320, Windows XP Pro SP2.

I don't know if it is due to the incompatibility between the special BIOS of the server motherboard and Grldr? Is there a way to solve it?

My IMG file is 2.88M, Grldr is 0.97, Memdisk is from August 2005, and the content of Menu.lst is:

timeout 0
default 0

title haozi system works 2006
clear
kernel (hd0,0)/boot/grub/memdisk c=8640 h=2 s=36 floppy
initrd (hd0,0)/boot/grub/hz.img

title Boot from HDD
root (hd0,0)
chainloader +1

title Restart

Is the keyboard USB?

GRUB 0.97 has Memdisk built-in and can be used.

title haozi system works 2006
map --mem (hd0,0)/boot/grub/hz.img
map --hook
chainloader (fd0)+1
rootnoverify (fd0)

Here to report, I'm not sure what to say. This isn't a forum specifically set up for GRUB4DOS, so issues other than those related to GRUB4DOS can also be reported. Even so, I still want to say something. First, before reporting an issue, you should test the latest release. Maybe the latest release has already fixed the problem? Also, if it's already the latest release but there's still an issue, then you can test older releases. This can help the developers determine where the root cause of the problem is.

Thanks!
The keyboard is PS2.
Try again...

In the morning, I followed the suggestion from the 2nd floor to remove Memdisk and modified Menu.lst to:

color black/cyan yellow/cyan
timeout 0
default 0

title haozi system works 2006
map --mem (hd0,0)/boot/grub/hz.img (fd0)
map --hook
chainloader (fd0)+1
rootnoverify (fd0)

In addition to the slow boot speed, the keyboard still can't be opened. Just now, I downloaded the latest Grldr modified version under the guidance of the dot master, and I will try it in the afternoon.

In addition, I also tried to boot with the old version of Grldr, and the result was either a black screen with no response or a crash as soon as entering DOS. It seems this motherboard is too new.

But it should be said that the new version has better compatibility, and several computers that couldn't boot earlier can now be used. I strongly support all the masters to make persistent efforts and develop more stable and compatible versions.

The boot speed becomes slow, maybe you are using the GRUB pre5 package, use pre4 first

This afternoon, I used the official latest revised version of Grldr to boot DOS on a new workstation, but still couldn't use the keyboard. It's frustrating!
But it can boot normally on machines with the following motherboards:
Intel i820 (IBM desktop)
Intel i845 (Lenovo Kaitian 4600)
Intel i855GE (Asus M2 laptop)
Intel i865/915/945 (MSI)
Intel E7505 (MSI)
I'm in a film and television editing room, and the computer configurations are relatively high, especially several video servers and workstations. The motherboards used are all non-ordinary level products. The newly purchased Supermicro (SUPERMICR) X6DA8-G2 Intel E7525 DualXeon motherboard is even the top product in the Supermicro series motherboards this year. In order to ensure system security, I have to do various backups, and the direct booting of Grldr is relatively easy, but it still can't be compatible. I hope the masters can solve this problem.

The problem was solved with the help of Budian Master. For details, please refer here:

Thank you very much!
