Perhaps I missed something in your email.. But if you've loaded ADLO + Bochs BIOS then you have Int13 support. Why not run Grub from the flash disk then instead of etherboot+AA? Is it because of the speed?
yes. I have try several time. using the ADLO with Int13 support. when I using the LILO & Grub , I works with the IBM harddisk. but when I use the Flash IDE disk. always give me LI 01 01 01 ... with LILO. or with Grub, too slow. but with the etherboot+AA . it sounds great!. :-)
what exactly are you booting using AA patch? it seems to me that using his patch you simply by pass either lilo or grub.
as for lilo, it seems to me that your problem is that you install lilo using different system than you boot from so disk geometry changes and thus the "LI" error.
as for grub. well it is weird. are you getting any errors? it seems to me like bochs bios would need fixing.
btw: I assume you are using 16 bit PC BIOS modules from etherboot rather than 32 bit EBI modules from said package, right? Interesting. Opens lots of new possibilities.
