IBM will switch to use 858 instead of their 850 variant with future issues of their products. […] I can only guess why they didn't add 858 to their [[EGA.CPI|EGAx.CPI]], [[COUNTRY.SYS]], and [[KEYBOARD.SYS]] files in [[PC&nbsp;DOS&nbsp;2000]]. Many third-party applications are designed to work with 850 and didn't know about 858 at the time PC&nbsp;DOS&nbsp;2000 was released, so it's easier for everyone, but unfortunately it's not compatible.&nbsp;[…] As explained above, COUNTRY.SYS and KEYBOARD.SYS contain only two codepage entries for a given country in Western issues of DOS. (In Arabic and Hebrew issues there can be up to 8 codepages for one country, in theory there is no limit below the range of allowed codepages 1..65534).&nbsp;[…] The problem is that removing support for 850 might have caused compatibility problems with applications which are hard-wired to use 850. Adding 858 as a third choice to all the files would have increased the file and table sizes significantly. The COUNTRY.SYS file parser in MS-DOS/PC&nbsp;DOS [[IO.SYS]]/[[IBMBIO.COM]] sets aside a 6&nbsp;Kb (for DOS&nbsp;6) scratchpad to load all the info. This allows a maximum of 438 entries in a COUNTRY.SYS file to be accepted, otherwise you will get the message "COUNTRY.SYS too large.". The [[NLSFUNC]] parser does not have this limitation, and the file parsers in DR-DOS (kernel and NLSFUNC) also do not know of such a restriction. Older issues of MS-DOS/PC&nbsp;DOS even had a 2&nbsp;Kb buffer for a maximum of 146 entries.}}</ref>
