Hello UBCD-Users and developers,

If I prepare my USB Stick with the ubcd2usb tools in the tools dir
I can boot this USB-Stick at my notebook (IBM ThinkPad p42)
but I got an error:
---snip---
- InitDisk
Invalid Opcode at 0003 0001 ...
---snap---
if I try to start a freeDOS image. When freeDOS tries to
initalize the Disks the error (Invalid Opcode...) occurs.
How do I get it run and fix this problem?

btw: I have to set the boot order priority (IBM ThinkPad p42) to
1: USB HDD
2: ... any other
in order to boot from USB-Stick.

It does not boot with "USB FDD" or "USB CD"
as the first item in the boot order priority.
Does anybody know why or how to fix this?
Or how to prepare the USB-Stick as an "USB FDD"
or "USB CD" if this is a problem of the "init disks" process
of freeDOS?

I also have problems to boot a selfmade "win98se" (dos 7.10)
Bootdisk. Memdisk seems to redirect some interupts
---snip---
[...]
INT 13 08: Success, count = 1, BPT = f000:8d99
old: int13 = f00066d0 int15 = f00066d5
new: int13 = 9e400008 int15 = 9e400376
Loading boot sector... booting...
---snap---
and then nothing happens...
... and I have to reboot

btw: the images are working fine if I burn them
to a CD and boot from this CD... It seems to be difficult
to boot an USB-Stick as a harddisk, isn't it?

sounds like a memory management issue. I suggest you upgrade the freedos image

viewtopic.php?t=1422

Code:
INT 13 08: Success, count = 1, BPT = f000:8d99
old: int13 = f00066d0 int15 = f00066d5
new: int13 = 9e400008 int15 = 9e400376
Loading boot sector... booting...
---snap---
and then nothing happens...
... and I have to reboot


What is the size of the image (1.44Mb or 2.88Mb)??

There is "only" one image "dosubcd.igz/fdubcd.img"
but it happens with the version 3.40 _and_ version 3.42
(if i boot from my usb-Stick as a usb-hdd)

It happens either with 1.44mb or 2.88mb images... :-(

Try ubcd2usb in UBCD 5.0 beta and boot with USB HDD.

I encountered this before and it was due to the geometry made by makefatboot in UBCD V4.x.
