Re: [Freedos-user] uide versus virtualbox versus ls120 - was: DISGUSTED With "Pundits"!!

Hi! (BCCing Jack and Mr. Lego)

If I understand you correctly, you deliberately make
incompatible for many VirtualBox users in order to fix
it for a few users with LS120 drives with broken BIOS
support?

Can you give more details about the way in which the
BIOS of Christian Pfaller fails to report the LS120?
By the way, is it supported as LS120 or just as 1.4M?

Did anybody with connections to the VirtualBox community
or a bug reporting account report the lack of support
for this semi-undocumented BIOS flag byte to VirtualBox?

By the way, why do you publish that mr-lego.fd web.de
email address to the list? Did Christian ask for that?

I still wonder how THAT would by influenced by whether or not
UIDE caches the drive? Or does UIDE get the geometry wrong or
some completely different problem arises? Because I assume by
flag byte you mean the byte saying whether the drive exists?
