Phil, how come I can boot fine with 1 floppy disk into my FC2 system? I ran mkbootdisk after a fresh install of FC2 and that was all I needed to do, just like with red hat's of the past. I'm booting into FC2 with the floppy in the same way I would if grub/lilo were on the mbr so I don't think I have a streamlined/rescue type kernel on that floppy. All the modules that need to be loaded at boot time are being loaded. I'm confused as to why people are saying this is not possible, what am I missing in this discussion?
Ps. it's a 2mb floppy
This explains why you are able to make the boot disk.
I just tried what Jeff suggested and it created an image that was just a bit larger than a 1.44 floppy. I got the below. This is on an athlon laptop.
rw-r--r-- 1 root root 1474560 Jun 17 23:00 /tmp/myboot.iso
Jim,
That will fit on a 1.44 floppy:
1474560 / 1024 = 1440K
Cheers, Sean
Does this mean that my system comes up with the exact value co-incidentally? Or does this mean that mkbootdisk always tries to make the image reflect the size of a floppy? Would a larger than 1474560 vmlinuz and initrd fail or cut off the end of the file, post 1474560?
-rw-r--r-- 1 root root 190569 Jun 14 21:07 initrd-2.6.6-1.435.img -rw-r--r-- 1 root root 1203768 Jun 14 09:23 vmlinuz-2.6.6-1.435
1203768 + 190569 = 1394337
I did the below command and ended up with a larger image.
I burned the disk with the newer iso image, in order to see what was on the disk. This had the /isolinux directory and the trans.tbl file.
mkbootdisk 2.6.6-1.435 --iso --device /tmp/testboot.iso
Size of boot image is 4 sectors -> No emulation [root@jcsevern root]# ls -la /tmp/testboot.iso -rw-r--r-- 1 root root 1794048 Jun 19 00:00 /tmp/testboot.iso
Now I have a boot iso! I don't have a built in floppy on this laptop.
Jim
