I didn't do my math before :-(
I tried using the trick with my existing /dev/hdd loading as -hda.
It has BootMagic: W89, 3 x BB, Debian.
BootMagic came up but then BB started with some funny colorful pixels :-(
Perhaps I can try another graphics mode. OTOH the BB from the CD image starts fine.
Perhaps it's a graphics configuration problem.
So I will give it a try with the spare disk on the weekend.
A question to ETH: Do you expect any trouble if I install a BB on ID1 slave (/dev/hdd)
and later in qemu the disk is mounted as IDE0 master ?
ID1 slave is removable disk so I can let the children play with the computer without
risking my stuff.
My qemu only allows giving LBA parameters to -hda.
The showstopper naturally would be whether I can access the www using my qemu started
BB. Did you try that yet ?
Thanks Jack !
