BIOS developers done strange things such as hardcoding Win9x boot files. This makes me think that them might have hardcoded the way them allocate memory and using memdisk's memory while it still needs to access the memdisk would result in a crash. If a BIOS updates failes and you used not-100% manual then you do not know if it was because of the not-100% manual or if it would have happened also with following the 100% the manual. Because if the BIOS update failed with a not-100% manual following way then the person does mostly not reproduce the 100% manual following way and reports to public the results, even these results would be only valid for the one motherboard at it's revision. This is because people do not experiment and reproduce with BIOS as often as them do with software because it's risky and needs special tools for recovery. (Even worse with brazed flash rom chips.) Personally I would be glad if there would be "less magic" inside the BIOS, just an sd card with FAT (or other fileformat where open source drivers are available) where you can copy (backup) and exchange the rom file without performing magic and/or Dual BIOS where one is completely static and read-only for recovery purposes while the other one can be used to reproduce things as often as you like. > In general, it is bad if you have to load "fancy" drivers such > as USB, NTFS or network, between booting and flashing...

Better BIOSes have various fallback options, such as a second copy of the BIOS or a part which cannot be flashed which is able to load update floppies even after a failed BIOS update. I personally would say that floppy is best (if you still have a drive) followed by harddisk, CD/DVD and then USB. You should avoid loading EMM386 for compatibility reasons but HIMEM should be safe for most BIOS update tools as far as I remember... If your BIOS USB drivers are not stable, it might help to copy all relevant files to RAMDISK before updating the BIOS. You could even BOOT from a RAMDISK, using ISOLINUX / SYSLINUX and MEMDISK. In general, it is bad if you have to load "fancy" drivers such as USB, NTFS or network, between booting and flashing... It is much better if you can put your BIOS update files directly on the drive where you will boot from, so you need no extra driver.

Re: [Freedos-user] unload previsiously loaded exe and sys on fdconfig.sys
Do BIOS update 100 % step by step as the manual says. No experiments wit h DOS versions, TSR's, boot medium (if you shall use legacy floppy then do so). Otherwise you risk the BIOS update to fail as the developers did not thought about your modified use. Ok, well you can experiment if you have the equipment to remove the flash chip and to flash it from outside. -mr Fabrício Ceolin schrieb: > Hi, > > Thanks everybody. > > Reboot it's not a option.

Re: [Freedos-user] unload previsiously loaded exe and sys on fdconfig.sys
Hi, Thanks everybody. Reboot it's not a option. I'm creating a script for bios update. Part of process is access a TCP/IP net, but I need to free memory to run a update executable. I'll try using a TERMIN.COM and report it! Best regards!

Re: [Freedos-user] unload previsiously loaded exe and sys on fdconfig.sys
Hi, > I want free some freedos memory after using a packet driver > and others sys (under fdconfig.sys) and exe (like doskey). I recommend to have 2 different config sys menu items: With and without internet :-). Doskey should not be necessary, FreeCOM and 4DOS have built-in history... > There are any way to unload programs without reboot? Some tools which work with "snapshot and restore" of some system state can do this, and some "drivers" have a built- in unload option, but it is easier and more stable in the result to just reboot.

The best method is to use programs that provide unloading as option so that they can properly unload themself. If you have to use a program without such an option you may want to try out the TSR Utilities (freeware without source code) which save some important system data before you install the program, then try to unload the program later by restoring this data. This method doesn't work for all programs so you have to be careful with it. I think the TSR Utilities don't work with programs loaded in FDCONFIG.SYS but you could try whether that program can be loaded by DEVLOAD (on Eric's site, or on the FreeDOS software page) instead.
