Re: [Freedos-user] Help: Boot FreeDOS from the second pri. partition
Hi all, I have fixed that by using chain.c32 and append "boot 2 freedos=KERNEL.SYS". It boots FreeDOS successfully. Thanks.

Re: [Freedos-user] Help: Boot FreeDOS from the second pri. partition
Don't know to answer direcly your question, but know another way to boot freedos with grub4dos from any partition and to boot linux from under freedos with the same grub4dos. The last is what use every day. If the first partition (possible in an USB as well), you install freedos in the usual way, then run grub with grub.exe and grldr and write your options to load linux from the second (or other) partition (or drive). Only freedos must be in the low memory. If something is over 640 kb, grub will hung. One can also install grub4dos into MBR and simply copy kernel command.cometc on any partition you want and write your options to load any thing you want, freedos as well. first partition of the first drive will be (hd0,0) second partition of the second drive - (hd1,1) etc. this is root. chainloader /kernel.sys - this is the command. boot. Only not sure this will be a "correct" DOS, not a specialist :) 2012/3/26 Lee Eric > Hi all, > > I'm going to create an USB flash disk.

Silly question since it's hard to tell, but did you make sure that it's a primary, active partition? Or maybe SYS.COM wrote the boot sector wrong? (Or maybe your BIOS needs / doesn't need an MBR on USB?) Also, I think you can maybe? override the LBA detection with SYS.COM. You may have to fiddle with some SYS.COM settings. It's kinda a crapshoot. Sorry I'm not more help, this kinda of stuff is arcane and tediously difficult (to me). -- This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
[Freedos-user] Help: Boot FreeDOS from the second pri. partition
Hi all, I'm going to create an USB flash disk. Here's the partition structure. Device Boot Start End Blocks Id System /dev/sdb1 * 1 537911 268955+ 83 Linux /dev/sdb2 537912 1598793 530441c W95 FAT32 (LBA) /dev/sdb1 I used for installing boot loader(syslinux) and other small standalone utilities. /dev/sdb2 is used for FreeDOS and I have copied necessary files to the partition. Here's my syslinux.cfg in /dev/sdb1. UI menu.c32 TIMEOUT 300 default localboot MENU TITLE System Rescue Flash Disk LABEL memtest MENU LABEL Memtest86+ (4.20) KERNEL memtest LABEL freedos MENU LABEL FreeDOS 1.1 COM32 chain.c32 APPEND hd0 2 freedos=KERNEL.SYS LABEL reboot MENU LABEL Cold Reboot COM32 reboot.c32 LABEL local MENU LABEL Boot from local hard drive LOCALBOOT 0x80 But when select freedos label it reports "Failed to load the boot file". I remember that FreeDOS can be installed on other partitions. Can anyone tell me how to fix that? Thanks.
