...are some bugs or improvements in the copybs and boot sector handling (I thought those mysterious options like setbpb, will make any dos7 bs file work). I hope the information here could be useful to some developer. Thank all of you who give suggestions, especially Ady. -- Regards, Lu Wei IM: xmpp:luweitest at riotcat.org PGP: 0xA12FEF7592CCE1EA

Even simply copying DOS8 files to DOS7 formatted disk (I hope it excludes bootsector incompatibility) can make it bootable. So I think DOS8 may be better with FAT32. The Disk is 8G. -- Regards, Lu Wei IM: xmpp:luweitest at riotcat.org PGP: 0xA12FEF7592CCE1EA

That file would probably still say the operating system is on the primary drive's first partition, but this would no longer be true. This is what I understand.

Lu Wei, What Hard drive are you also trying to boot? The first and only fixed drive inside a computer? If so would the line to boot a local HD not be: LABEL LOCAL MENU LABEL Local operating system in harddrive (if available) kernel chain.c32 append hd0 -Adan On Thu, Apr 4, 2019 at 8:56 AM Adan Calderon <adancalderon at gmail.com> wrote: > > Lu Wei, > > For the DOS portion

Greetings, I encounter a problem that should be basic, but I can't get a clue. I have 8G USB disk formatted as FAT32. I run (syslinux -i -s -r -m H:) to make it bootable, and write syslinux.cfg according to the documents, but it will not boot some items. Syslinux is 6.03, bios files used. The whole syslinux.cfg file:

Greetings, I am a new use of R, starting from R-commander. I find that the default quantile-comparison (Q-Q plot) of R-commander has no group option, and I happened to notice RcmdrPlugin.plotByGroup in the packages list. As the name is so explicit, I installed it, loaded it, R-commander restarted, but the 3 menu item under Graphs->plot by group are all greyed out. What could be wrong? --
