Hello Bart, >> Checking MSDOS 6.2, the kernel doesn't move the EBDA if no UMB is >> found.
BO> MSDOS 7.10 does move the EBDA though. What MSDOS are we looking at now -- BO> the FAT16 kernel says 5.0, and the FAT32 says 7.10 ? it's not a matter of reported kernel version - and I don't care about it. as you said a while ago, 'make as many programs happy as possible. MSDOS 7.1 doesn't move it on F5 (or ctrl-F5 ? should this depend on the kernel version ?), but seems to move in himem. didn't research for long, as I don't consider that important. >> in the default setting, moving the EBDA doesn't save any memory; >> setting switches /E:512 might enable 'MOVEEBDA' and would save low memory BO> Lucho had his reasons to implement it in the first place -- It doesn't save a single byte in the default setting; it actually even costs 16 precious bytes only SWITCHES /E:992 starts to save some bytes if not moving to UMB. the problem I reported (softice /EMM) would be handled nicely if the EBDA was moved on config_end(). Softice moved the EBDA around itself (for whatever reason), end the sanity checks would take care of that. the move_ebda_around is also much more useful, if it would be done after EMM386/UMBPCI, so it could go to UMB. BO> I have no idea BO> why we suddenly have all these problems surfacing after >6 monts. neither do I - thats life. BO> I also wonder if we don't have a bug somewhere? I can't remember stories BO> of people being forced to use "SWITCHES=/E" for Windows 98. google for NOMOVEXBDA BO> I agree it's probably safer to not move it by default but I'd like to BO> know where the problem really is. there is no known protocol 'I have moved the EBDA, leave it as it is' I have also no idea, how a warmboot is supposed to succeed after move_ebda() tom BO> ------------------------------------------------------- BO> This SF.net email is sponsored by: The Robotic Monkeys at ThinkGeek BO> For a limited time only, get FREE Ground shipping on all orders of $35 BO> or more.
