Measure with a multimeter or continuity tester.<\/p>\n\n\n\n<p>For small solder joints on through-hole components, use flux if possible; it makes life easier and increases the quality of the connection.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Probleme\"><\/span>Problems<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"XTIDE_wird_beim_Booten_nicht_gefunden\"><\/span>XTIDE is not found on boot<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul>\n<li>This is usually due to an address conflict, either with the ROM or because the wrong HDD controller address was specified. Even if the controller isn't found, XTIDE simply won't be displayed. Check all addresses again, and also check the jumpers on the ROM and controller boards. C800 and D800 have proven to be good values for the ROM address.<\/li>\n\n\n\n<li>Incorrect ROM used, some EPROMs and EEPROMs are not compatible. Cards can also only support the specified EPROM types. For example, I replaced a 27C256 with a 28C256, but it didn't work because the pinout deviates in two places. A 27C257 must be used here ;).<\/li>\n\n\n\n<li>When it comes to the ROM on the network card, ensure that it is active, that the size and address are set correctly.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Controller_nicht_gefunden\"><\/span>Controller not found<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Should the XTIDE be displayed unexpectedly, but the error \"Controller not found\" appears, then the address\/type of the IDE controller is incorrect; check this again in the tool and re-flash the ROM.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Checksumm_Error\"><\/span>Checksum Error<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>XTIDECONF did not run, this calculates the checksums and sets them.

If you try to flash the AT28C64, the version on it will no longer work afterwards and the EPROM programmer must be used.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Fazit\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<p>Sch\u00f6ne kleine Karte, erf\u00fcllt ihren Zweck und ist nicht teuer. Die Verwendung eines EEPROM macht die Karte weitaus flexibler als ihre <a href=\"https:\/\/www.fambach.net\/en\/retro_pojekt-rom-isa-karte\/\" data-type=\"post\" data-id=\"12601\">ROM Version<\/a>. Auch die Wahl zweier unterschiedlicher ROM-Gr\u00f6\u00dfen ist ein sch\u00f6nes Beiwerk. St\u00e4nde ich vor der Wahl zwischen der ROM und der EEPROM version, w\u00fcrde ich mich f\u00fcr die EEPROM Version entscheiden. Der Preis liegt nur ein paar Cent h\u00f6her, f\u00fcr die zus\u00e4tzlichen Bauteile und der Platine Preis ist der Gleiche.<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><thead><tr><th>Description<\/th><th>Worth<\/th><\/tr><\/thead><tbody><tr><td>Successful<\/td><td>Yes<\/td><\/tr><tr><td>Price per piece<\/td><td>~4\u20ac<\/td><\/tr><tr><td>Soldering time<\/td><td>0,5 Stunden<\/td><\/tr><tr><td>Function<\/td><td>Super<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">Conclusion to the project<\/figcaption><\/figure>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Verwandte_Beitrage\"><\/span>Related Posts<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n<ul class=\"display-posts-listing\">\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/retro_pojekt-isa-boot-isa-boot-eeprom-karte\/\">Retro Project \u2013 ISA Boot EEPROM Card<\/a><\/li>\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/retro_pojekt-mini-isa-rom-karte\/\">Retro Project \u2013 Mini ISA ROM Card<\/a><\/li>\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/retro_pojekt-xt-cf-lite-version-4-1\/\">Retro Project \u2013 XT-CF-Lite Version 4.1<\/a><\/li>\n<li class=\"listing-item\"><a class=\"title\" href=\"https:\/\/www.fambach.net\/en\/retro-xt-ide-bios\/\">Retro \u2013 XT-IDE (BIOS)<\/a><\/li>\n<\/ul>\n\n\n\n<h1 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Quellen\"><\/span>Sources<span class=\"ez-toc-section-end\"><\/span><\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">To the project<\/h2>\n\n\n\n<p><a href=\"https:\/\/www.vogons.org\/viewtopic.php?t=82499\">Vogonen Link<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/www.vogons.org\/download\/file.php?id=115166\"><\/a><a href=\"https:\/\/www.vogons.org\/download\/file.php?id=117234\">ISA-BOOT-EEPROM v0.1.zip<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/github.com\/wiretap-retro\">Herausgeber<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/spdx.org\/licenses\/CC-BY-4.0.html#licenseText\">CC-BY-4.0<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/rayer.g6.cz\/romos\/romos.htm\">https:\/\/rayer.g6.cz\/romos\/romos.htm<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/github.com\/ki3v\/xtramtest\">https:\/\/github.com\/ki3v\/xtramtest<\/a><\/p>\n\n\n\n<p class=\"wp-embed-aspect-16-9 wp-has-aspect-ratio\"><a href=\"https:\/\/www.youtube.com\/watch?v=uBpgABajHdw\">https:\/\/www.youtube.com\/watch?v=uBpgABajHdw<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Retro pages<\/h2>\n\n\n\n<p><a href=\"https:\/\/archive.org\">https:\/\/archive.org<\/a> \u2013 Old software, magazines, manuals, and much more.<\/p>\n\n\n\n<p><a href=\"https:\/\/theretroweb.com\">https:\/\/theretroweb.com<\/a> \u2013 PC Hardware Directory.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.winhistory.de\/index.php\">https:\/\/www.winhistory.de\/index.php<\/a> \u2013 DOS, Windows Version Descriptions.<\/p>\n\n\n\n<p>Win 3.1x Tools and Tricks<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Retro Forensics<\/h2>\n\n\n\n<p><a href=\"https:\/\/forum.classic-computing.de\/forum\">https:\/\/forum.classic-computing.de\/forum<\/a> \u2013 German\/English forum with many retro computer enthusiasts.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.vogons.org\">https:\/\/www.vogons.org<\/a> \u2013 I have found many tips on hardware here, they also have a driver directory.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.dosforum.de\">https:\/\/www.dosforum.de<\/a> \u2013 Forum with strict rules and very helpful regarding DOS, Windows questions are not welcome.<\/p>\n\n\n\n<p><a href=\"https:\/\/dosreloaded.de\">https:\/\/dosreloaded.de<\/a> \u2013 DOS, hardware repairs, BIOS files and more.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.winhistory-forum.net\">https:\/\/www.winhistory-forum.net<\/a> DOS and Windows history.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Retro Shops<\/h2>\n\n\n\n<p><a href=\"https:\/\/ram-co-shop.de\">https:\/\/ram-co-shop.de<\/a> -
