Hi Abe,

if you like, take a look at:

https://www.lazybrowndog.net/freedos/virtualbox 


There are three VirtualBox images of FreeDOS 1.1. 

I put quite some effort in them to make them work. I remember the crash you are 
talking about, but, sorry, I don’t remember how I fixed it (wasn’t it something 
about not loading high something?? Very sorry. Maybe you compare the 
AUTOEXEC.BAT and FDCONFIG.SYS of the FreeDOS 1.1 VirtualBox image?

Eric,

Thanks for your time and attention. See my responses inline.

I understood JEMMEX to be the preferred option. Yes, the other boot 
options all work.

Can you point me in the direction of a good resource where I could learn 
about adjusting the JEMMEX options/settings?

Why are the JEMMEX defaults not set to work with a 
fresh install? Or does it work for most people, and my 3 computers just 
happen to all not work?

Perhaps I should allocate more than 32MB of RAM to avoid this collision? 
I will try that too.

They are the stock options found in the C:\FDCONFIG.SYS file:

1 - Load FreeDOS with JEMMEX, no EMS (most UMBs), max RAM free
2 - Load FreeDOS with EMM386 (Expanded Memory) and SHARE loaded
3 - Load FreeDOS including XMGR XMS-memory driver
4 - Load FreeDOS without drivers

I have not altered C:\FDCONFIG.SYS.

This means that JEMMEX (EMM386) tried to allocate UMB but
predicted troubles. Soon after that, DOS does indeed hang.
I suggest to select a boot option without JEMMEX instead.

Alternatively, you could change the JEMMEX options in your
config.sys to more cautious settings regarding UMB areas.
Then you get at least some UMB and thus more free DOS RAM.

> I don't believe this is related to the UIDE driver...

It is possible that the same memory area where JEMMEX tries
to allocate UMB is also in use for disk, network or UMB I/O
buffers of your virtual hardware... So it is possible that a
crash is more likely with UIDE (more modern disk I/O) but a
better solution compared to avoiding UIDE would be to select
more cautious JEMMEX options regarding that memory region.

> Boot options 2,3,4 all work without issue.

What are the names of boot options 1, 2, 3 and 4 respectively?

[Freedos-user] FreeDOS 1.1 crashing in VirtualBox 5.0.22

2016-06-27 Thread Abe Mishler 
Dear List,

I've attempted to install FreeDOS 1.1 using VirtualBox 5.0.22 on 3 
different machines with 3 different operating systems: (Macbook Pro 
(10.11.5), Windows 8.1 Home, and Windows 10 Pro). On each system, upon 
bootup and selecting option 1, I get the following message:

JemmEx v5.75 [05/21/11]
System memory found at c900-dfff, region might be in use
JemmEx loaded
Kernel: allocated 46 Diskbuffers = 24472 Bytes in HMA

after which nothing ever happens. It hangs permanently. I don't believe 
this is related to the UIDE driver as suggested in the installation Wiki 
pages because of where it freezes. Regardless, I installed the VBOX-FIX 
COM patch on the Windows 10 Pro setup and it didn't solve the problem.

Boot options 2,3,4 all work without issue.

Has anyone else run into this? Your help in understanding (& fixing!) 
this is greatly appreciated.

Thanks,
Abe

[Freedos-user] FreeDOS 1.2 Preview 21

2016-06-27 Thread Jerome E. Shidel Jr. 
Hello All,

I have just released Preview 21.

This is only a minor preview update. Mostly these things:

installed configuration for FDNPKG now points to the 1.2 repository.
a couple of additional utilities by Eric Auer are included as EXTRAS on the big 
USB and CD image.
some release building improvements 

You can download it from either http://up.lod.bz/FDI  or 
http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.2/previews/1.2-pre21
