Wonderful job translating the article, things are nicely explained in it. However, the original question still stands, and I seem to have the same problem, namely: - I have Win98SE (no patches as far as I know, other than the one for large disk access) on an EPOX EP-8KRAI with an Athlon XP, with 2GB RAM in two sticks (DDR400, PC3200). Used to have 512MB, without problems up to the upgrade; - After the customary MaxPhysPage and MaxFileCache restriction to 40000 (1GB) and 524288, windows boots nicely, no immediate apparent problems - but MS-DOS produces the "not enough memory error", no matter what I do. - I've tried EVERYHING, nothing makes DOS work. - AGP aperture is 64MB; tried to reduce to 32MB: no luck - VCache down to 32768 changes nothing, below that windows starts to refuse to boot (not enough memory). The setting is applied correctly, verifiable with System Monitor. - PhysPage as 60000 (1.5GB) does not boot at all; as 3C000, 30000 or even 20000 (back to 512MB!!!) does not help. windows boots, DOS does not work. The setting is applied correctly, verifiable on every about page and with System Monitor. ...now what? I'd rather not physically remove RAM, because I'm dual booting with XP which is fine thank you and makes good use of it. Any ideas, please...? - Max
