Hi, Aladdin used to work perfectly fine on my DOS PC. I just had to setup EMM386.EXE with EATXMS to restrict to 16MB.
Then the CMOS battery died, and I tried to configure the BIOS back to the best of my recollection. Everything else seems to be working back fine, except Aladdin. It runs, but it's unplayably slow. The intros, the menus, everything. Any ideas?
Video BIOS caching/shadowing?

Tried enabling/disabling both, no difference.
Some BIOSes, having the turbo mode set high or low in setup overrides or flips the sense of the turbo switch, so if you had it boot turbo on low, then you thought one setting was high, one low, so you've left it on high, but when you reset CMOS it went back to high and low setting is now high.
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.
Double check A20 gate is set to fast/chipset. Maybe this game does lots of switching of this?

No turbo mode on this PC - it's a Socket370 Via C3 PC. Aladdin isn't speed sensitive, so should not be facing any issues on that aspect.

Tried Normal, and Fast. No difference.
A sec0nd game that requires EMS - CyberPuck3D - has also stopped working. All other games are working fine. So definitely either some setting in the BIOS is interfering with EMM386, or the RAM has suddenly gone bad.

So try to check memory using MemTest86+

I just swapped the RAM, but still no difference. This is just so weird. Both games worked perfectly fine before the CMOS battery died. Got to be a BIOS setting that's interfering with EMM386.
I switched to JEMMEX.EXE with the MAXEXT option, and both games work fine now. I'm still curious to what BIOS option is interfering with EMM386.EXE + EATXMS, since that combination worked perfectly for over a year. But I'm happy the problem is solved, for now.
