Re: Best machine settings for Q2Dos?

I test whole batch of Dosbox, Wmware, Virtualbox and QEMU 4.2 DOS machine on some real HW.. and only PCem its only one with these very long loading times and very slow menu, so something is not right, i even tried same disc images with Virtualbox so its not about some DOS 7 configuration mistake.

Re: Dos 7.1 FAT32 HDDs data corruption / disk operations related freezes. SCSI boot is not working

Hmm, i did more testing, but so far no corruption with SCSI and FAT16 with IDE, so it really seems as problem with FAT32 + IDE only and maybe only with bigger disks, or Socket 7 platform, or only MS-DOS 7.1 - all these things together. Update: SCSI is work around.. but present ISA SCSI controller ha...

Hello,
all modern virtualization tools, has growable image files, pleas add support for it too. At least some disk image resize options would be good.
